Abstract

Optimum conditions for the glycolysis of polyurethane flexible foams and elastomers are reported. The crude, two-phase liquid reaction mixture was separated and the upper phase was used as the polyol component of an industrial adhesive mixture. During glycolysis the formation of carbon dioxide was recognized and quantified. On the basis of this new finding a novel reaction mechanism is proposed for the glycolysis of polyurethanes.
