Abstract:
A composition comprising from 10 to 90 weight percent of a copolyetherester elastomer comprising: a modified, random polybutylene terephthalate copolymer block that is derived from a polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate, polyethylene terephthalate copolymers, and combinations thereof; and that contains at least one residue derived from the polyethylene terephthalate component; and a polyalkylene oxide copolymer block that is derived from the polyethylene terephthalate component and a polyalkylene oxide glycol, and that contains polyalkylene oxide and at least one residue derived from the polyethylene terephthalate component; from 10 to 90 weight percent of a polycarbonate; and from 0 to 60 weight percent of a polyester.
