Abstract

See full text

Compositions of biobased polymer blends of polymers of polybutylene succinate (PBS) or polybutylene-adipate-terephthalate (PBAT) and a polyhydroxyalkanoate copolymer are described. In certain embodiments, the copolymer is a multiphase copolymer blend having one phase a glass transition temperature of about −5° C. to about −50° C. Methods of making the compositions of the invention are also described. The invention also includes articles, films and laminates comprising the compositions.
