Molecular weight control of polyurethane elastomers |
摘要 |
Polyurethane elastomers are prepared by reacting organic polyisocyanates with organic polyhydroxyl compounds and a mono-functional secondary hydroxyl group containing chain terminator. The chain terminator can be added to the polyhydroxyl compound prior to the reaction with the polyisocyanate.
