POLYHYDROXYALKANOATE COMPOSITION EXHIBITING IMPROVED IMPACT RESISTANCE AT LOW LEVELS OF IMPACT MODIFIER

摘要

The present invention relates to impact modifiers in polyhydroxyalkanoates (PHA's), including polylactic acid (PLA). The impact modifiers comprise mixtures of a core-shell impact modifier and a glycidyl methacrylate containing ethylene copolymer (GMA copolymer). Improved impact performance is realized at low levels of total impact modifier.
