ABSTRACT:
Copolyesters blended with ethylene/carboxylic acid copolymer in which at least 10% of the acid groups are neutralized have increased melt strength, and are more readily processable by blow molding and extrusion film blowing techniques. The blends contain from 0.2 to 20% by weight of the ethylene/acid copolymer.
