Abstract
Thermoplastic polyurethane-polymer compositions having improved elastic properties are prepared by reacting hydroxylated diene polymers with diisocyanates in the presence of about 10 to 50% of a diamine, based on the total weight of hydroxyl-terminated diene polymer and diamine, said diamine being a mixture of disecondary diamines and secondary-tertiary diamines and said mixture comprising 1 to 10% secondary-tertiary diamines.
