Polyols hybrids of PhD / PMPO for applications of polyurethane foam

摘要

Abstract invention patent: "polyols hybrids of PhD / PMPO for applications of polyurethane foams. The present invention relates to polyols polymer hybrids.These polyols polymer hybrids include the product of free radical polymerisation of (a) a polyol base comprising (1) a polyol modified with polymers selected from (a) dispersions of poliureias and / or poly - hidrazodicarbonamidas in a compound containing hydroxyl group And (b) polyols of polyaddition of poly isocyanates, and optionally, (2)A polyol having a functionality of 2 to 6, and a number of Oh of from 20 to 500; (b) optionally a stabilizer preform; and (c) one or more etilenicamente unsaturated monomers in the presence of (d) a free radical polymerization initiator, and (E) optionally. An agent Control of polymer.The present invention also relates to a process for the preparation of polymeric polyols hybrids, foams prepared from these polyols polymer hybrids and to a process for the preparation of these foams.
