Abstract:
A thermoplastic vulcanizate, comprising:a blend of about 20 to about 30 parts by weight of an engineering thermoplastic selected from the group consisting of polyester, polycarbonate or polyphenylene oxide, or combinations thereof each having a melting point or glass transition temperature from about 160.degree. C. to about 260.degree. C. or more; andfrom about 70 to about 80 parts by weight of an acrylate rubber, ethylene-acrylate rubber, or combinations thereof, having pendant or terminal carboxylic anhydride functionality crosslinkably reactive with and at least partially crosslinked with a multifunctional oxazoline, oxazine, imidazoline, or combinations thereof which crosslink said rubber and do not degrade said engineering thermoplastic,wherein said parts by weight are based upon a total of 100 parts by weight of said thermoplastic and said rubber.
