Abstract
Vulcanized blends of EPDM rubber and aromatic polyester are provided by melt extruding mixtures of aromatic polyester, such as polyalkylene terephthalate and functionalized EPDM reactive rubber pairs. An EPDM functionalized with epoxy groups can be vulcanized with an EPDM rubber functionalized with thermally labile ester groups capable of generating epoxy reactive carboxylic acid.
