Abstract
A polar thermoplastic and acrylate or ethylene acrylate based polar rubbers form a useful thermoplastic vulcanizate when the rubber is selectively cured with curatives which do not affect the polar thermoplastic and do not generate volatile organics. Examples of thermoplastics include aromatic polyesters, polycarbonates, poly(phenylene oxide), or combinations thereof. Examples of curatives include compounds with a multifunctional oxazoline, oxazine or imidazoline, which can react with functional groups such as carboxylic acid groups on the rubber.
