Hydroxyalkanoatpolymerzusammensetzungen

摘要

There is provided a highly biodegradable resin composition comprising a hydroxyalkanoate polymer and a crystallization nucleating agent. The resin composition may typically comprise a hydroxybutyrate homopolymer or a hydroxybutyrate-hydroxyvalerate copolymer and an aromatic amino acid. There is also provided a device prepared by using such a resin composition. The resin composition of the invention is capable of undergoing a crystallization at a high speed to provide the article molded therefrom with improved properties. The resin composition is also highly degradable in an animal body or in the environment.
