Abstract: This invention relates to a process for preparing polyol-containing dispersions by reacting polyurethane-urea waste with at least one linear and/or branched-chain diol and/or polyol with a mol mass of 50-1000 g/mol in a ratio by weight of polymer waste to diol and/or polyol of greater than 3:1 at a temperature of 150.degree.-250.degree. C., optionally in the presence of acid or basic catalysts, and by dispersing the reaction product in at least one primary polyol with a mol mass up to about 6000 g/mol.The resultant dispersions are suitable for the preparation of polyurethanes or polyurethane-ureas.
