POLYISOCYANATE PREPOLYMERS AND POLYURETHANE PRODUCTS OBTAINEDTHEREFROM |
摘要 |
Polyisocyanate prepolymers for use in preparing polyurethane products elastomers, adhesives and foams, are prepared by combining (1) organic polyisocyanate with (2) polyols which are the hydroxyl-terminated digestion products of (a) waste or scrap polyalkylene terephthalate polymers and (b) organic polyols. Polyurethane products resulting from the polyisocyanate prepolymers exhibit useful and unexpected properties. |
