Polyurethane based on epoxy-containing polymer polyol and process for making the same |
摘要 |
Polyurethane resins having high rigidity and improved physical properties such as mechanical strengths and heat resistance are obtained by reacting a polyisocyanate with a polymer polyol derived from an epoxy-containing monomer, for example, glycidyl esters of unsaturated mono- and dicarboxylic acids, and a polyol, and bringing about ring-opening reaction of epoxy radicals in the presence of an epoxy curing agent, simultaneously with, or before or after the urethane-forming reaction.
