Abstract

Process for the preparation of polyurethane elastomeric polymers, characterized in that it comprises reacting together a substantially linear polyhydroxy compound with a molecular weight greater than 800 and an excess of 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate, to form a isocyanate terminated prepolymer; mixing the prepolymer with a low molecular weight diol, diamine, or hydroxyamine; and continue the reaction until obtaining a solid product.
