PREPARATION OF CELLULAR POLYURETHANE ELASTOMERS USING POLYETHER CARBONATE DIOLS AS A STARTING COMPONENT

摘要

O.Z. 0050/42160 A process for the preparation of cellular polyurethane elastomers involves reacting a) an organic and/or modified organic polyisocyanate with b) a polyether polycarbonate diol which contains bonded polyoxytetramethylene glycol radicals having a mean molecular weight Mn (number average) of from 150 to 500, and, if desired, c) a low-molecular-weight chain extender and/or cross linking agent, in the presence of d) a blowing agent, e) a catalyst and f) if desired additives and/or assistants.
