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.
