Biodegradable optically active polymers and intermediate oligomers thereof, and process for producing them |
摘要 |
An optically active oligomer obtained by polycondensation of an (R)-3-hydroxyalkanoic acid alkyl ester and at least one of a diol, a diamine and an amino alcohol and an optically active polymer obtained by copolymerization of said oligomer and a monomer selected from diisocyanic acid esters, dicarboxylic acid derivatives, and dichlorosilanes are disclosed. Novel functional polymers with biodegradability and hydrolyzability are produced with industrial advantage.
