The present invention relates to compositions comprising blends of alkenyl aromatic polymers such as styrenic polymers (i.e. PS and HIPS) and bio-based or biodegradable polymers (i.e. PLA, PGA, PHA, PBS, PCL) compatibilized with styrene-based copolymers (i.e. styrene-ethylene-butylene-styrene (SEBS) block copolymers, maleated SEBS, styrene-maleic anhydride (SMA) copolymer, styrene-methyl methacrylate (SMMA) copolymer) or a mixture of two or more styrene-based copolymers such as SEBS and SMA. These novel compositions can be extruded and thermoformed to pr...
What is claimed is: 1. A thermoplastic composition comprising:a polymer blend of:at least one alkenyl aromatic polymer in the amount between about 10 to 90 percent by weight of the blend;at least one bio-based or biodegradable polymer selected from polylactic acid and copolymers thereof or polyglycolic acid and copolymers thereof in the amount between about 10 to 90 percent by weight of the blend; andat least two blend compatibilizers comprising a first blend compatibilizer selected from the group consisting of styrene-ethylene-butene-styrene and maleate...
