摘要： A process for the preparation of recyclate polyols obtained by glycolysis of polyurethanes and/or polyurea-polyurethanes comprises metering in monofunctional and/or difunctional glycidyl ethers over the entire course of the reaction; the low-amine recyclate polyols obtained in this way are used for the preparation of cellular or noncellular polyurethanes.
