Abstract
Process for preparing polyurethanes polymers consisting in reacting in a first stage a polyether polyol or a mixture of polyols polyethers on an organic polyisocyanate, the quantities of reagents being such that there is a significant excess of nco isocyanate functions and in a second stage a polyester polyol or a mixture of polyester polyols on the polymer formed in the course of the first stage, the amount of polyester polyol being such that after the reaction still remain free nco isocyanate functions.
