Abstract
A polylactic acid composition is provided having a polymer matrix and a compatibilizer. The polymer matrix includes polylactic acids and acrylonitrile-butadiene-styrene[s]. The compatibilizer is at least one compound selected from the group consisting of: a poly (styrene-ethylene-butadiene-styrene) copolymer grafted with maleic anhydrides, an acrylonitrile-butadiene-styrene copolymer grafted with maleic anhydrides, a polystyrene grafted with maleic anhydrides, and an ethylene-ethyl acrylate-glycidyl methacrylate.
