Document Type and Number:
WIPO Patent Application WO/2022/266787
Kind Code:
A1
Abstract:
Disclosed is a process for preparing a polyurethane product, comprising: providing an isocyanate component (i), and an isocyanate-reactive component (ii) comprising at least one unsaturated linear diol represented by Formula (I), at least one polyol other than the unsaturated linear diol, and at least one free radical initiator having a decomposition temperature above 120°C; and subjecting the above stated components to a multi-stage thermal treatment. The polyurethane product thus prepared can exhibit superior mechanical strengths even at an elevated temperature, decreased internal heat buildup, improved heat resistance, and desirable manufacture cost. A polyurethane product prepared by the process and a composition for preparing the polyurethane product are also provided. HO-R1-C (R2) =C (R3) -R4-OH Formula (I)
