In this work, the viscoelastic properties of epoxy polymers modified with hexagonal boron nitride were studied. The calculated elastic modulus is compared with its experimental value. It has been established that boron nitride does not significantly affect the glass transition temperature of epoxy polymers

The dependence of the modulus of elasticity on temperature for epoxy polymers with different content of thermoplastic is shown. The effect of a thermoplastic modifier on the average glass transition temperature of cured epoxyamine binders has been studied.

In this paper, the rheokinetics of curing processes in epoxy amine binders modified with PSFF-70K carding polysulfon copolymer is studied in the regime of permanent shear and oscillation. The used curing agent is 4,4'-diaminodiphenylsulfon. The viscosity growth constants and gel formation activation energies are calculated.

In this paper, viscoelastic properties of epoxy polymers modified with polysulfone carding copolymer have been studied. The dependence of the modulus of elasticity on temperature for epoxy polymers with different content of thermoplastic has been shown. The effect of a thermoplastic modifier on the average glass-transition temperature of cured epoxyamine binders has been studied.

The adhesion strength of epoxy-binder—steel-fiber joints and the change of binder mechanical properties under multiple cyclic curing have been studied. It has been shown that the adhesion strength monotonically decreases with an increase in the number of cycles when the curing temperature is much higher than the binder vitrification point. In this case, the mechanical properties of the matrix are also decreased. Some possible mechanisms of the observed changes are also discussed.

The properties of epoxy polymers modified with polysulfones and polyethersulfones have been studied by dynamic mechanical analysis and dilatometry. Modified systems have a reduced modulus of elasticity, which is probably due to a decrease in the final degree of cure in presence of the thermoplastics. The resulting epoxy resin-thermoplastic systems have a relatively high glass transition temperature and a higher level of residual stresses compared to neat cured ED-20.

The effect of fillers, polysulfone and polyetherimide, on the mechanism and kinetics of the thermo-oxidative degradation of a composition based on an epoxy oligomer cured with 4,4'-diaminodiphenyl sulfone which proceeds under heating in the nonisothermal regime is studied. A relationship is revealed between the structure of the composition and the mechanism and kinetic parameters of the process, on one hand, and the chemical nature of the filler, on the other hand. Mechanistic and kinetic features of the nonisothermal degradation of the epoxyamine composition are ascertained by the thermoanalytical method using differential scanning calorimetry. The kinetic parameters of the process are assessed by an analysis of thermokinetic curves in terms of thermokinetic models and the examination of oxidation products. Depending on the filler nature and composition structure, reactions involving bonds of interjunction chains and junctions of the network of the epoxy polymer as well as radical reactions of the active centers of the filler occur in the polymer during thermal oxidation. An increase in the network density and the localization of the filler determine the contribution of the diffusion factor, decrease the rate of thermo-oxidative degradation of interjunction chains, and increase the rate of breakdown of network junctions.

The effect of heat-resistant thermoplastics (mixtures of polyetherimide and polycarbonate) on the adhesion of epoxy resin ED-20 to fibers and its wetting ability, as well as on the residual stresses arising at the adhesive–solid interface during the bonding formation was studied. It has been shown that the introduction of mixtures of thermoplastics practically does not affect the change in wetting during curing, reduces residual stresses, and increases the adhesive strength in bonding of ED-20 to fibers. Plausible mechanisms of the observed synergism of the strength of the interface are discussed.

The Department for plastics processing was established by order of the Ministry of education in 1960 at the Mendeleev Moscow Institute of chemical technology. In 2020, the Department of plastics processing technology of the Mendeleev Russian state technical University celebrates 60 years since its foundation. A brief overview of the history of the Department's formation is presented.

The results of rheokinetic, dynamic mechanical, and calorimetric investigations of the process of curing of an epoxy oligomer ED-20 blend with epoxyphosphazene by a low-molecular-weight polyamide L-20 are analyzed. It is shown that the phenomenological curing kinetics of all studied systems is characterized by the presence of two stages of the process: a second-order reaction followed by a self-retarded second-order reaction upon reaching the isothermal glass transition of the system.

The effect of a statistical copolymer of propylene and ethylene on the tensile strength of polypropylene was investigated.

The effect of additions of pure and modified montmorrilonite on the polypropylene crystallization rate was studied within the framework of Avrami model. In the presence of these fillers in amounts of 2.5–5.0 wt %, both the crystallization rate and the degree of crystallinity increase, and at the content of these fillers increased to 10% and higher values these parameters decrease. Introduction of fillers enhances the mechanical properties of polypropylene, which allows the developed material to be recommended for the production of packaging film.

The possibility of application of different mathematical models used to describe the dependence of viscosity and conversion on the curing time, as well as the rheokinetics of curing of an epoxyamine compound, is considered. It is shown that viscosity growth in the process of curing is determined by the degree of conversion and temperature.

The effect of nanosized carbon additives on the properties and crystallisation of polypropylene was investigated. It was shown that the introduction of carbon nanoparticles affects the crystallisation rate and the properties of polypropylene.

The process of curing an epoxyamine composite was investigated by methods of dynamic mechanical analysis and rotational viscometry. The service characteristics of the cured composites depend on the curing process and are directly related to the process kinetics and to change in the rheological characteristics.
