    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.

    Abstract: Polyurethane elastomers are formed from first and second graft curatives, each graft curative having a molecular weight of at least about 800, wherein the first and second graft curatives are substantially immiscible with one another, and wherein the polyurethane elastomer exhibits a hardness of less than about 40 Shore A according to ASTM D2240-86 and a compression set of less than about 8% according to ASTM D395-89, method B, at a temperature of about 70° C. for about 22 hours. Rolls are manufactured using such polyurethane elastomers, particularly rolls that are suitable for use in image forming devices, such as electrophotographic print applications.
