Several polyurethanes were prepared from polyethylene adipate glycol, 4,4'-diphenylmethane diisocyanate, 1.4-butanedio1, and 3,3'-dichloro-4,4'-diaminodiphenylmethane. The temperature dependence of swelling and dynamic mechanical properties were determined. Analysis of the data shows that microphase

Several polyurethanes were prepared from poldethylene adipate) glycol, 4,l'diphenylmethane diisocyanate (MDI), and 1,4-butanediol. The overall NCO/OH ratio was allowed to vary from 0.94 to 1.21. Thus, the obtained elastomers differed in the amount of allophanate groups and perfection of microphase s

A new class of poly(amide-imide-urethane) thermoplastic elastomers based on two-step synthesis of 4,4@-methylene bis(4-phenylisocyanate) with di †erent polyols (PPG and PTMG) and trimellitic anhydride was synthesized. Both resulting polymers showed semicrystalline structures and were readily soluble
