Polyester compositions useful to improve the impact and heat distortion properties of polyethylene terephthalate, providing the polyethylene terephthalate with both high notched Izod properties and high heat distortion properties. The composition is the reaction of a terpolymer of ethylene, an acrylate or a methacrylate, and glycidyl methacrylate with polyethylene terephthalate in the presence of at least one elastomer such as a copolymer of ethylene and 1-octene.
