摘要:
A process for preparing a recyclate polyol obtained from glycolysis of polyurethanes and/or polyurea-polyurethanes comprises reacting scrap polyurethane and/or polyurea-polyurethane with a short-chain compound containing at least 2 OH groups in the presence of a catalyst and admixing a cyclic carbonate. The process results in a recyclate polyol having a low primary aromatic amine content which may be used to produce cellular or non-cellular polyurethanes, polyurea-polyurethanes, or polyisocyanurates.
