ABSTRACT:
Disclosed are blends of about 99 to about 10 weight % of poly(ethylene terephthalate) and about 1 to about 90 weight % of a polyester of trans-4,4'-stilbenedicarboxylic acid and at least one aliphatic glycol having 2 to 16 carbon atoms. The blends have improved gas barrier properties and improved chemical resistance.
