Abstract: Biodegradable compositions of polybutylene-succinate (PBS) or polybutylene-succinate-adipate (PBS A) with biobased 3-hydroxybutyrate copolymers are described. In certain embodiments, the copolymer increases the biodegradation rate of the PBS or PBSA. Methods of making the compositions of the invention are also described. The invention also includes articles, films and laminates comprising the compositions.

Abstract: Polymer systems comprising poly(vinyl chloride), a non-petroleum based filler, and a polyester additive, wherein the polymer system is highly filled, and articles made therefrom, are described. The high loading of filler (e.g., talc, calcium carbonate or a combination thereof) is achieved by incorporation of polyester additives such as polyhydroxyalkanoates. High filler loading without significant reduction of relevant material properties can be associated with cost savings and environmental benefits.
