A stabilization effect of petroleum polymer resin on the thermal oxidation of high-pressure polyethylene was found with the frustrated total internal reflection infrared spectroscopy method and from the analysis of physicomechanical properties. The kinetics of thermal oxidation and the rate of decrease in physicomechanical properties of polymers in the presence of an Irganox 1010 conventional industrial polyolefin stabilizer and C5–C9 petroleum polymer resin were analyzed comparatively.

The influence of petroleum resin on the thermal oxidation of an ethylene copolymer with vinyl acetate was studied with differential scanning calorimetry, FTIR infrared spectroscopy, and physicomechanical tests. We found that the introduction of PPR into EVAC inhibits the accumulation of oxygen-containing groups in the polymer. The use of the resin combined with an Irganox 1010 primary antioxidant makes it possible to maintain the performance of a material after holding at higher temperature for 3 h at a significantly higher level than in the case of only Irganox 1010.

Composites based on high-pressure polyethylene and ethylene–vinyl acetate copolymer containing a sepiolite clay powder with a chain-layered structure are studied, and an analysis of their physical and mechanical properties is carried out. No organomodification and compatibilization are required in the case of using sepiolite. It is shown that composite materials with the addition of sepiolite are superior with respect to a series of characteristics to composite materials containing conventionally applied layered clay powders.

We present a review and analysis of publications focused on the scientific prediction of adhesive interaction using the thermodynamic characteristics of the joined surfaces. The main theoretical characteristic of the adhesion of two different phases is the thermodynamic work of adhesion. This value can be measured by wetting methods in the presence of a liquid phase or by calculations. The main disadvantage in establishing the correlation is the very approximate agreement between the theoretical and experimental values of the adhesive strength. Methods for calculating the work of adhesion using quantum-chemical simulation and modeling of molecular dynamics are now widely used. We propose an original method for determining the work of adhesion for polymer–metal joints, which makes it possible to establish a correlation with the adhesive interaction value, which, in turn, is estimated by the cathodic-disbondment method.

Old preserving coatings of polymer glue based on phenol–formaldehyde resin and polyvinyl butyral were removed from the surface of a number of archaeological metal objects by the electrochemical method of cathodic peeling (peeling under conditions of cathodic polarization). Optimal conditions have been selected for carrying out an experiment without violating the integrity of the artifact. The purification carried out made it possible to almost completely remove the damaged coating and preserve the specific corrosion layer.

The effect of a polyethylene blend composition and concentration of polar components of ethylene copolymers with vinyl acetate and copolymers of ethylene/vinyl acetate/maleic anhydride on some properties of high-pressure polyethylene compositions with these copolymers is discussed. It is shown that, for the blends under investigation, the character of the adhesive strength dependence determines the vinyl acetate content in the polar copolymer. It is established that the presence of anhydride units in the polar copolymer increases the absolute adhesive strength of the composition without affecting the nature of its dependence on composition of the polyolefin blend.

Various components and parameters of the free surface energy of a large number of polymer and metal surfaces have been estimated using the van Oss—Chaudhury–Good theory by the method of wetting with test liquids. All data are obtained by spatial processing of the specified equation. The values of the thermodynamic work of adhesion of polymer adhesives on metals have been calculated theoretically. The adhesion interaction of the polymer composite material–metal studied joints has been studied by the method of peeling under conditions of cathodic polarization. The correspondence between the adhesive strength of the joints and the work of adhesion of the polymer adhesive and metal has been found.

A series of clays are studied as potentially effective fillers for polyolefins. For the purpose of achieving good interaction with the polymers, surface-energy and acid–base properties of clay powders are evaluated using the preferential wetting method. It is shown that the surface of the clay acquires a neutral character as a result of the modification.

Systems consisting of ethylene–vinyl acetate copolymers and (aminoalkoxy)silanes are studied. The diffusion and mutual solubility of their components are investigated, and phase diagrams covering a broad range of composition and temperatures are constructed. We find that the near-surface layers of the modified copolymers are enriched with the organosilicon component. The effects that the phase structure of considered adhesives has on the energetic properties and adhesion strength for different types of substrates are identified.

A comprehensive study of composite materials based on a copolymer of ethylene with vinyl acetate in the presence of petroleum resins (PRs) has been carried out. The effect of PRs on the acid–base, physicomechanical, and adhesive properties of the compositions has been evaluated. It has been found that, in the presence of PRs, both the relative elongation at break and the tensile stress of the samples increase. The adhesive properties of modified polymer coatings on steel evaluated by the method of cathode peeling for some compositions also increase (the diameter of the defect decreases).

Data on the surface-energy, acid–base, and thermal characteristics of a wide range of oil–polymer resins have been obtained using wetting methods and differential-thermal analysis. The composition of resins is determined by nuclear magnetic resonance on protons. The dependence of acid–base properties (acidity parameter) of the resin surface on the content of olefinic protons has been found. Samples with best thermal stability are noted.

Studies have been carried out to increase the adhesion and heat resistance of insulating tape coatings based on chlorobutyl rubber applied on pipelines. It is shown that the synergistic effect of the growth of adhesion of chlorobutyl rubber to steel by the co-administration of the oligomer of 2,2,4-trimethyl-1,2-dihydroquinoline and polymeric petroleum resin is due to the increased interaction of the oligomer with chlorobutyl rubber under the action of a polymeric petroleum resin and the high adhesion of the oligomer to steel.

The adhesive interaction of some polymer surfaces with neutral, acidic, and basic samples formed on a cantilever specimen has been evaluated via atomic-force microscopy. The thermodynamic work of adhesion has been calculated using the Johnson–Kendall–Roberts model. The differences in the work of adhesion values obtained in the interaction of acidic, basic, and neutral samples with the same polymer surface have been found. The experimentally obtained values of work of adhesion have been carefully compared with theoretically calculated ones, which allowed the conclusion to be drawn that the area of research under consideration is promising.

The results of studies on the use of an excimer laser with a wavelength of 193 nm are presented for the treatment of surface of polymers to improve adhesion. It is shown that the radiation of coherent waves in the ultraviolet range leads to a change in surface topography and increase in its specific area, which contributes to increasing the mechanical adhesion; in addition, laser exposure activates the surface of the polymers, intensifying adsorption adhesive interaction.

An original procedure to determine the surface energy characteristics of various disperse modifiers used in polymer compositions based on the selective wetting of powders with test liquids and neutral hydrocarbon is proposed. Surface free energy and its components, as well as acidic and basic parameters for a number of polymer additives, are evaluated.

Surface free energy and its components for the oxidized and unoxidized metallic surfaces are determined under selective wetting conditions using test liquids and neutral hydrocarbons. A well-distinguished oleophily of the surfaces under study due to their molecular nature is established. A preliminary thermal oxidation surface does not significantly affect the surface characteristics.

In order to eliminate the influence of atmospheric adsorption, the surface free energy of some metal substrates is determined under conditions of selective wetting. The dependence of obtained values on surface tension of used neutral hydrocarbon is found. A well-defined hydrophobicity of these surfaces before and after thermal oxidation is established.

Surface energetic and acid-base properties of coatings based on copolymers of ethylene with vinylacetate are studied. It is shown, that acid-base interactions have determining role in adhesion interaction on the interface with metal.
