  • Silane vulcanized thermoplastic elastomers
    Patent number: 6448343
    Abstract: The formation of thermoplastic vulcanates may be accomplished with two polymers, wherein one polymer is grafted, or copolymerized with a carboxylic acid anhydride, which acid anhydride grafted polymer then is reacted with an amino silane, which reacts with the acid anhydride and then cross links.
