Abstract

Prezenta inventie se refera la un procedeu de obtinere a unor elastomeri poliuretanici termoplastici, pe baza reactiei de poliaditie si prin tehnica de prepolimer nestocabil, plecând de la polietilenglicoladipat, 4,4'-dibenzildiizocianat de glicoli micromoleculari. Materialele obtinute pot fi prelucrate prin injectie, extrudere si alte procedee proprii termoplastelor, procedee rapide, cu consum relativ mic de energie, cu posibilitati de recirculare a deseurilor. Procedeul conduce la elastomeri poliuretanici care au un continut scazut de diizocianat si îsi mentin proprietatile fizico-mecanice la un nivel ridicat.
