摘要: The model polyurethane foam and compact material were prepared then decomposed by means of natural oils. Castor oil fish based polyol used in this study. Optimal conditions for the decomposition found. Temperature 250 °C was necessary efficient castor whereas 200 is sufficient case polyol. Prepared products have hydroxyl number range 95–168 mg KOH g−1. During no cleavage double bonds fatty acid chains observed.
