摘要：
A polyester polyol is formed in a polycondensation reaction between an aromatic dicarboxylic acid, a polyol, and an epoxy compound having a straight chain alkyl or alkenyl group having at least six carbon atoms. The polyester polyol exhibits excellent compatibility with hydrocarbon blowing agents. As such, it is a useful component in rigid polyurethane foam formulations that are contain hydrocarbon blowing agents.
