Thiodiethanol based polyurethane elastomers having improved dynamic

Thiodiethanol-based polyurethane elastomers having improved dynamic

Vulcanizable elastomeric compositions derived from thiodiethanol and more particularly, vulcanizable elastomeric compositions comprising the reaction product of a major proportion of thiodiethanol and a minor proportion of a low molecular weight, hydroxyl terminated aromatic or cycloaliphatic polyester.

Vulcanizable elastomer from thiodiethanol and an oligomeric polyester

Vulcanizable elastomeric compositions are disclosed which are the reaction products of 80 to 90 mole percent of a mixture of thiodiethanol and one or more aliphatic or cycloaliphatic diols and 20 to 10 mole percent of an aromatic or cycloaliphatic dicarboxylic acid wherein the diol content is at least 50 mole percent thiodiethanol and about 1 to 10 mole percent of a diol providing pendant allylic unsaturation.
