RESIN COMPOSITION AND COMPATIBILIZER

摘要

PROBLEM TO BE SOLVED: To provide a resin composition originated from a monomer derived from an organism, and having heat resistance, and to provide a compatibilizer for compatibilizing a polylactic acid with a poly(α-methylene-γ-butyrolactone). SOLUTION: The resin composition contains a polylactic acid/poly(α-methylene-γ-butyrolactone) graft polymer and a poly(α-methylene-γ-butyrolactone) obtained by carrying out a radical polymerization ofα-methylene-γ-butyrolactone in the presence of a polylactic acid. The compatibilizer of the polylactic acid with the poly(α-methylene-γ-butyrolactone) comprises the polylactic acid/poly(α-methylene-γ-butyrolactone) graft polymer obtained by carrying out the radical polymerization of theα-methylene-γ-butyrolactone in the presence of the polylactic acid.
