摘要：
The invention relates to a process for the preparation of recyclate polyols by reacting rigid polyurethane foam with short-chain hydroxyl-containing compounds, which comprises adding at least one epoxidized native fatty oil to the reaction mixture after glycolysis at a temperature from 10.degree. to 80.degree. C. below the glycolysis temperature.
