Abstract

Polymeric blends of polystyrene (PS) and polylactic acid (PLA) are described, in the preparation of which a compatibilizing agent was added, preferably a PS-PLA block copolymer. Such compatibilizing agents act controlling phase separation of the blending compounds, and preventing excessive growth of polystyrene domains scattered in the PLA matrix; and this results in blends with good mechanical and thermal resistance.
