摘要：
A high impact thermoplastic polyblend of a polyethylene terephthalate, a polyester elastomer, and an aromatic phosphite. The aromatic phosphite when added in amounts up to as much as about 5 percent by weight of the total polyblend composition causing grafting of the polyester elastomer onto the polyethylene terephthalate chains producing a thermoplastic polyblend composition having superior impact strength.
