摘要： High molecular weight linear thermoplastic elastomeric polyurethanes of I.V. 0.9-2 are prepared by reaction in solution. A hydroxyl-terminated prepolymer and a diol chain extender are reacted, in the solvent, with a small excess of diisocyanate, until the -NCO content becomes constant, then a diol chain extender in amount equivalent to the remaining -NCO; reaction is continued, and then terminated after the high I.V. is attained.
