Compositions based on polyether - polyols and their application for the preparation of polyurethanes foams

摘要

P compositions based on polyether - polyols and their preparation processes. / p & & p & these compositions are obtained by reacting a dialcohol or a polyalcohol with an oxide of the olefin or alpha - epoxide in préscnce of a basic catalyst, in particular potassium hydroxide. The basic catalyst is neutralized with oleic acid or of the tall oil fatty acids, alone or in combination with a sulfonic acid, in particular an acid alkylbenzene - or alcoyltoluènesulfonique of high molecular weight, with an acid butyl - or amylnaphtalènesulfonique. / p & & p & application to the preparation of polyurethane foams. / p
