ABSTRACT:
Copolyesters blended with ethylene/carboxylic acid copolymers and a polycarbodiimide have increased melt strength, and are more readily processable by blow molding and extrusion film blowing techniques. The blends contain up to 20% by weight of the ethylene/acid copolymer. The acid groups may be partially neutralized to a level of about 10%.
