摘要：

Two methods are developed for thermochemical degradation of castable polyurethanes to recover raw materials and improve the ecological situation. Degradation products are analyzed by IR spectroscopy, and degradation mechanisms are proposed. Castable polyurethanes are prepared from polyesters containing degradation products.
