Abstract
A thermoplastic polymer blend having improved impact performance includes from about 50 wt % to about 98 wt % polyethylene terephthalate (PET), a polymeric toughening agent and a compatibilizer. The compatibilizer is a functionalized polyolefin, a thermoplastic copolymer or a thermoplastic terpolymers. The ratio of wt % compatibilizer to wt % polymeric toughening agent, based on the total weight of the thermoplastic polymer blend, is from about 0.1 to about 0.4.
