Abstract: The properties of melt blends of specific aliphatic-aromatic copolyesters and starch are improved by addition of a combination of polylactic acid, graft copolymers such maleic anhydride grafted polyethylene and maleic anhydride grafted polystyrene, and a hindered phenolic antioxidant. The blends exhibit increased melt strength and maximum draw down ratio versus blends of only aliphatic-aromatic copolyesters and starch. Films made from the blend are compostable and exhibit an attractive combination of mechanical and rheological properties for packaging materials.

Abstract: Blends comprising 65-95 wt % poly(trimethylene terephthalate-co-sebacate), 5 to 35 wt % polylactic acid and a chain extender are provided that exhibit greatly increased melt strength compared to that of poly(trimethylene terephthalate-co-sebacate) alone. Such improvements allow these compositions to be processed readily by melt-blowing, which is useful for packaging and for preparing items such as biodegradable garbage bags.

Abstract: Polyester compositions based on 1,3-propanediol and aromatic and aliphatic diacids that can contain a large fraction of biologically derived content are disclosed. Transesterification between polyesters in blends of such compositions is greatly reduced using phosphorous-containing additives. The blends have properties similar to poly(ethylene terephthalate).
