POLYSTYRENE AND POLYLACTIC ACID BLENDS

摘要

The invention describes polymeric blends of polystyrene (PS) and polylactic acid (PLA) to which a compatibilising agent is added, preferably a PS-PLA block copolymer. The compatibilising agents have the effect of controlling phase separation between the blend components, preventing excessive growth of the polystyrene domains dispersed in the PLA matrix, leading to the production of blends having satisfactory thermal and mechanical resistance.
