摘要: Thermoplastic polyurethanes are formed from a polydiene diol, preferably hydrogenated polybutadiene having 1.6 to 2 terminal hydroxyl groups per molecule and number average molecular weight between 500 20,000, an isocyanate two molecule, optionally chain extender molecule. The thermoplastic polyurethane composition is prepared by prepolymer method, solventless method using the branched extender.
