The regular trends in chemical degradation of rigid polyurethane foam under the action of oxypropylated hydroxy compounds were studied. The molecular-weight characteristics, functionality with respect to 4,4′-diphenylmethane diisocyanate and OH groups, viscosity, and the content of terminal OH groups of alcoholysis products at temperatures from 150 to 220°C were determined. A mechanism of degradation of the network structure of rigid polyurethane foam was suggested.
