A polyhydroxyalkanoate copolymer composition is provided. The composition comprises a plurality of polyhydroxyalkanoate copolymer molecules. The polyhydroxyalkanoate copolymer molecules (i) comprise 3-hydroxybutyrate monomers and 4-hydroxybutyrate monomers, (ii) have a monomeric molar percentage of 4-hydroxybutyrate monomers of 23.5 to 75%, and (iii) have a biobased content of &#x2265;80%. Also provided is a method of making a polyhydroxyalkanoate copolymer composition. The method comprises culturing an organism in the presence of one or more carbon raw materials under conditions under which (a) the one or more carbon raw materials are converted to 3-hydroxybutyryl-CoA and 4-hydroxybutyryl-CoA and (b) the 3-hydroxybutyryl-CoA and the 4-hydroxybutyryl-CoA are polymerized to form the polyhydroxyalkanoate copolymer molecules, thereby forming the composition. The organism has been genetically engineered to comprise particular enzymatic activities, and to not comprise other particular enzymatic activities. The one or more carbon raw materials, taken together, have a biobased content of &#x2265;80%.

Polyhydroxyalkanoate copolymer compositions and methods of making the same

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 &#x2212;5&#xb0; C. to about &#x2212;50&#xb0; C. Methods of making the compositions of the invention are also described. Also articles, films and laminates made from the compositions are described.
