| 摘要 | Polyvinyl ester) block copolymers comprising blocks of two or more different vinyl ester repeating units. The vinyl ester repeating units may be wherein R is H, C1-C22 straight or branched alkyl or alkylhalide, or phenyl or substituted phenyl, and n is 10 to 12,000. Methods of making polyvinyl ester) block copolymers, including reversible-addition fragmentation chain transfer, organobismuthine-mediated living radical polymerization, and cobalt mediated radical polymerization. Chemically-degradeable and biodegradable polymers comprising polyvinyl ester) block copolymers. | ||||||
