Patent ID: 7291677

Claim:
An adherent, reactively modified thermoplastic elastomeric blend formed from the dynamic vulcanization of a material comprising a propylene resin, an ethylene/alpha-olefin/non-conjugated diene copolymeric elastomer component, and a bonding agent, in the presence of a curing system comprising: a free radical initiator; a first co-agent comprising one or more multifunctional acrylates containing at least two acrylate groups, multifunctional maleimides containing at least two imide groups, or mixtures thereof; and a second co-agent comprising syndiotactic 1,2-polybutadiene, atactic 1,2-polybutadiene, high vinyl solution styrene-butadiene elastomer, or mixtures thereof; wherein the free radical initiator and the first and second co-agent are collectively present in an amount sufficient to provide a gel content of the elastomeric blend of at least about 97 percent and to provide blends of the invention that are adherent with a minimum peel strength of at least about 650 g/cm to a polar material, wherein the elastomer component contains ethylene in an amount of about 40 to 75 percent by weight.
