Synthesis and Copolymerization of Benzamide Methacrylate with Styrene
A new monomer, benzamide methacrylate, is synthesized, and its free radical copolymerization with styrene in mass and in a solution in benzene in the presence of azobisisobutyronitrile (AIBN) is carried out and investigated. The ratio of comonomers is varied in a range of 90 : 10–10 : 90 mol %. The total concentration of comonomers is 1.7 mol/L at 70°C. The composition of the synthesized copolymers is determined by elemental analysis based on the nitrogen content. The monomer and copolymer are characterized by spectroscopic methods (IR, nuclear magnetic resonance (NMR)). The values of the relative activity constants of the monomer are determined, and the Alfrey–Price parameters are calculated. To assess the nature of distribution of the links in the macromolecular chain, the parameters of the microstructure are calculated. It is found that r1 > r2 (r1 and r2 are the relative activity constants) in all the cases; therefore, the copolymer is enriched in benzamide methacrylate links. It is shown that the composition of the formed copolymers depends on the composition of the initial monomer mixture. The obtained copolymer possesses quite high medical and biological activity, which opens up the possibility for its use as bactericides and fungicides. The obtained copolymers based on benzamide methacrylate are nontoxic and can be used as bactericidal agents. It is found that the biocidal effect is first of all associated with the presence of benzamide fragment links in the macrochain.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
