Abstract
Compositions of biobased polymer blends of polymers 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. Also articles, films and laminates made from the compositions are described.
