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.

Compositions comprising recyclate blends of polymer recyclate and polyester additives are described. In certain embodiments, the polyester additive is a PHA such as a poly-3-hydroxybutyrate-co-4-hydroxybutyrate copolymer having a weight percent 4-hydroxybutyrate of 8.5-45%. In other embodiments the PHA is mixed with the recyclate polymer at concentrations of 10-50% by weight of the recyclate blend. Methods of making the compositions of the invention are also described. The invention also includes articles made from the recyclate blends.

Patent
Metabolix | Date: 2013-12-02

Compositions of polymer blends of polyvinylchloride (PVC), a low molecular weight plasticizer and polyhydroxyalkanoate (PHA) are described. In certain embodiments, the PHA is a poly-3-hydroxybutyrate-co-4-hydroxybutyrate copolymer having a weight percent 4-hydroxybutyrate of 30-45%. In other embodiments the PHA is a multiphase P3HB-4HB copolymer blend having one phase fully amorphous. The PHA is mixed with the PVC and low molecular weight plasticizer to optimize the PVCs optical, thermal and mechanical properties. In certain embodiments, the polymer is branched with optionally additives that improve properties. Methods of making the compositions of the invention are also described. The invention also includes articles, films and laminates comprising the compositions.


Methods and genetically engineered hosts for the production of 3-carbon, 4-carbon and 5-carbon products, polymers and copolymers in methylotrophic bacteria are described herein.


Gamma-butyrolactone (GBL) and Gamma-hydroxybutyrate (GHB) having a unique carbon footprint as defined by the percent modern carbon (pmc) are described herein. The percent modern carbon can be controlled by varying the amounts of biobased, renewable starting materials and petroleum-based starting materials to prepare GBL or GHB having a defined pmc or by preparing mixtures of GBL or GHB prepared from biobased renewable starting materials and GBL or GHB prepared from petroleum-based starting materials.


Methods and genetically engineered hosts for the production of poly-4-hydroxybutrate and 4-carbon products are described herein.
