Patent ID: 8735505

Claim:
A composition comprising: from 10 to 90 weight percent of a copolyetherester elastomer comprising: a modified, random polybutylene terephthalate copolymer block; and a polyalkylene oxide copolymer block that is derived from a polyalkylene oxide glycol, and that contains polyalkylene oxide; wherein the copolyetherester elastomer comprises diethylene glycol groups in an amount ranging from 0.1 to 10 mole %, based on 100 mole % of glycol in the copolyetherester elastomer; and wherein the polyalkylene oxide copolymer block comprises poly(1,4-butylene oxide); from 10 to 90 weight percent of a polycarbonate; and from 0 to 60 weight percent of a polyester.
