ABSTRACT:
Graft polymer curatives comprise a side chain having an average molecular weight of at least about 500, a main chain having an average molecular weight of less than about 200, and diol functionality on the main chain. The graft polymer curative is formed via free radical polymerization of at least one ethylenically-unsaturated monomer with a chain transfer agent or initiator.
