Abstract:
A polymer composition comprising a thermoplastic polyurethane and a first olefin graft polymer, the olefin graft polymer including at least one first graft moiety and at least one second, non-silane containing graft moiety, the first graft moiety being a silane moiety that promotes crosslinking of the grafted elastomer in the presence of moisture, the second graft moiety being an unsaturated organic compound that, prior to grafting, contains at least one ethylenic unsaturation and a polar functionality that promotes compatibilization of the olefin and the thermoplastic urethane, each unsaturated organic compound, prior to grafting, being at least one compound independently selected from the group consisting of vinyl ethers, vinyl-substituted heterocyclic compounds, vinyl oxazolines, vinyl amines, and unsaturated carboxylic acids and anhydrides, ethers, amines, amides, succinimides and esters of such carboxylic acids.
