Title: MOLDED PARTS CONTAINING A POLYLACTIC ACID COMPOSITION
Abstract:
A molded part that is formed from a thermoplastic composition that contains a polylactic acid, propylene/α-olefin copolymer, and a polyolefin compatibilizer is provided. The propylene/α-olefin copolymer can be dispersed as discrete physical domains within a continuous matrix of the polylactic acid. Without intending to be limited by theory, it is believed that the discrete domains can help resist the expansion of the composition during a molding operation, which minimizes the degree of expansion experienced by the composition during molding in comparison to conventional polylactic acid compositions.
