Chemical reactions of unsaturated and macromolecular compounds

Abstract

1. The conditions for the copolymerization of acid methacrylic with alkyl vinyl ethers have been investigated, and a number of new copolymers have been synthesized. 2. It has been shown that the copolymerization processes of unsaturated compounds in which there are functional groups having mobile hydrogen axe accompanied by a number of side reactions. 3. It has been shown. that acylals are formed in the course of the copolymerization process. 4. It has been established that screening of the carboxyl groups of the original methacrylic acid can be effected either by reaction of the methacrylic acid with alkyl vinyl ethers, or by copolymerization with the latter, or by addition of alkyl vinyl ethers to carboxyl groups of the copylymer. 5. It has been shown that, when suitable mixtures of methacrylic acid and alkyl vinyl ether react in presence of benzoyl peroxide, polymerization and copylymerization processes may predominate over side reactions. 6. In the course of investigations of the copolymerization of methacrylic acid and alkyl vinyl ethers, it has been shown that new copolymers, having hydrophilic (COOH) and hydrophobic (OR) groups, are formed. 7. It has been established that under these conditions alkyl vinyl ethers do not polymerize in presence of benzoyl chloride.
