Abstract
A thermoplastic elastomer that is adherent to polar materials may be made from a dynamically vulcanized blend of propylene resin, ethylene/alpha-olefin/non-conjugated diene elastomers, and a bonding agent via a curing system containing a free radical initiator, at least one co-agent including multifunctional acrylates containing at least two acrylate groups, multifunctional maleimides containing at least two imide groups, or mixtures of both, where the elastomer gel content in the modified blend is at least about 97 percent. Reaction mixtures, articles made therefrom, and methods of dynamically vulcanizing are also disclosed.
