PREPARATION AND STUDY OF COPOLYMER OF N,N'-(p-PHENYLENE) BISMALEIMIDE WITH ALLYL ESTER OF SALICYLIC ACID

Abstract

The reaction of radical copolymerization of N,N'-(p-phenylene)bismaleinimide with allyl ester of salicylic acid was carried out. Conditions of the implementation of the copolymerization reaction, the rate, content and molecular weight of the obtained copolymers, as well as the dependence of these parameters on the composition of the initial mixture of monomers determined. It established that the copolymerization reaction was accompanied by the formation of donor-acceptor complexes between monomer pairs. The copolymerization reaction proceeded on radical-complex mechanism and the relative activities of monomers in the copolymerization reaction calculated: (r1=0.03; r2=0.04). The copolymerization constant values close to zero indicate the tendency of the monomer to copolymerization reaction and the formation of macromolecules with alternating structure analyzed. The composition and structure of the obtained polymer was determined by methods of physical-chemical and spectral analysis, and also its antibacterial properties studied. It found that in spite of the fact that the investigated polymer showed an active effect on separate cultures of microorganisms in the case of concentrate, it had weak antimicrobial activity. It also revealed that the effect of the polymer on the cells of fungi (C.albicans) is more effective.
