摘要： A process for preparing a hybrid polyester-polyether polyol comprises contacting a carboxyl group-containing component and an epoxide, optionally in the presence of one or more of a double metal cyanide catalyst, a superacid catalyst, a metal salt of a superacid catalyst and/or a tertiary amine catalyst, under conditions such that a hybrid polyester-polyether polyol is formed. The hybrid polyester-polyether polyol offers the advantages of both ester and ether functionalities when used in a polyurethane formulation, thus enhancing physical properties. The process results in products having narrow polydispersity, a low acid number and unsaturation, and reduced byproduct formation, particularly when the double metal cyanide catalyst is employed.

摘要： Polyurethane polymers are made from a reaction mixture that contains a polyisocyanate, a hydroxylmethyl-containing fatty acid or ester, and another polyol, polyamine or aminoalcohol. The carboxylic acid or ester group on the hydroxymethyl-containing fatty acid or ester are capable of engaging in a variety of reactions with the polyisocyanate and/or amine or hydroxyl groups present in the reaction mixture. This allows for good quality, high molecular weight polymers to be produced even though the hydroxymethyl-containing fatty acid or ester tends to be a low functionality material.
