Imido class is the multi-functional class and naturaly it has some microbiological features to give attention towards studies. For this objective, imido-group containing maleimide-polymeric structures of [4-N-Phenylethanamideazo-3-N-(4-bromophenyl) maleimide [em-PABMI] and N-[{4-(N'-benzenesulphonicacid) amino-carbonyl}-3-chlorophenyl]maleimide[em-BSACChPMI] synthesized byconventional method. Copolymerization was done by using acrylic acid (AA) as a comonomer for both compounds, via an efficient and effective emulsion polymerization procedure to form an emulsion of copolymers. In this process,both monomer] were firstly prepared by using maleic anhydride as a brick unit and other suitable and needful reagents were used and copolymers [em-CPABMI] and [em-BSACChPMI] were synthesized using aqueous free radical initiator. The structures of monomer and copolymers were confirmed by FT-IR, 1H-NMR spectroscopy. Antimicrobial activities were also performed to analysis polymer's specialty and their significances.

Imido-functional group contenting N-[{4-(N’-benzenesulphonicacid) amino-carbonyl} phenyl] maleimide was prepared by reacting species of maleic anhydride, 4-amino benzoic acid and 4-amino sulphanilic acid via chlorination in the presence of Diphosphoruspentaoxide (P2O5) as a catalyst in medium of N, N’-dimethyl formamide (DMF). Homopolymer, copolymers[C1BSACPMI], [C2BSACPMI], [C3BSACPMI] and terpolymers [T1BSACPMI], [T2BSACPMI] were prepared by reaction of [BSACPMI] monomer with three different of acrylates, namely acrylonitrile (AN), acrylic acid (AA) and vinyl acetate (VA) in presence of tetrahydrofurane (THF) polar organic solvent. The structures of these compounds were confirmedby FT-IR, 1 HNMR. The weight average molecular weight (Mw), number average molecular weight (Mn) and polydisperity (Mw/Mn ratio) of polymers were determined using Gel Permeation chromatography (GPC) technique. Thermal susceptibility of all polymers were studied by Thermo Gravimetric Analysis (TGA) and DSC techniques. All polymers wereevaluatedfrom biological activities against some bacterial and fungal species.

Maleimide modified epoxy compound was prepared by reacting copolymer of Acrylic acid (AA) of N-[(4-acetyl)phenyl]maleimide (APMI) maleimide APMI-co-AA with epichlorohydrin in presence of Triethylamine (TEA). The resulting compound possessed both the oxirane ring and maleimide group. Synthesized epoxy maleimide resins characterized by FT-IR, 1H-NMR spectroscopy. Thermal stability of uncured resins was evaluated by TGA and DSC analysis. Glass fiber reinforced composites was also prepared and their chemical and mechanical properties were checked out. Resultant cured sample have good thermal stability, chemical resistance (acid/alkali/solvent) and water absorption resistance properties.

Epoxy based vinyl ester resins were synthesized by reacting with methyl acrylate (MA) / ethyl acrylate (EA). The estrification reaction of epoxy resin was carried out using triethylamine (1 percent of total weight of epoxy resin) as a catalyst and 0.03% of hydroquinone as an inhibitor at 90C-100C. The synthesized resins are structurally characterized by FT-IR and HNMR spectroscopic methods and their resultants show good solubility in polar solvent.

The present article deals with the synthesis of phenolic epoxy resin by the reaction of phenolic resin and epichlorohydrin. The synthesis of phenolic resin was carried out by using p-ethylphenol, formaldehyde and naphthol. The structures of phenolic and epoxy resins were confirmed by spectroscopic analysis. The synthesized epoxy resin showed solubility in polar solvents like DMF, dioxane, acetone, DMSO, THF, ethyl acetate, and chloroform. Thermal characterization of epoxy resin was monitored by differential scanning calorimeter (DSC) using curing agent and thermo gravimetric analysis (TGA). Molecular weight of the resin was evaluated by gel permeation chromatography (GPC).

In order to prepare a new polymeric structure of [4-N-Phenylethanamide azo-3N-(4-nitrophenyl) maleimide [NPAMI] and polymerization was done by using styrene (Sty) and methylacrylate (MA) as a comonomers via an efficient and effective emulsion polymerization procedure to form an emulsion of copolymer. In this process, monomer [NPAMI] was firstly prepared by using maleic anhydride with other needful, suitable reagents and synthesized by addition mechanism. The structures of monomer and copolymers were confirmed by CHN, FT-IR, 1H-NMR spectroscopy. Keyword: Polymeric structure, Copolymer, Maleic anhydride, Styrene, Methylacrylate
