摘要： A process to convert a secondary hydroxyl-capped polyol to a primary hydroxyl-capped polyol comprises reacting a polyether polyol, polyester polyol or polyether-ester polyol with a cyclic anhydride of a polycarboxylic acid, to form a half acid ester is formed, followed by reacting the half acid ester with ethylene oxide, to form a polyester polyol or a polyether-polyester polyol. Both steps are carried out in the presence of an amine catalyst and a double metal cyanide complex catalyst. The process offers high primary hydroxyl functionality (for example, up to 95 percent, based on total functionality) with low amounts of ethylene oxide as a reactant (for example, less than 5 percent by weight).
摘要翻译：将仲羟基封端的多元醇转化为伯羟基封端的多元醇的方法包括使聚醚多元醇，聚酯多元醇或聚醚 - 酯多元醇与多元羧酸的环状酸酐反应，形成半酸酯，然后使半酸酯与环氧乙烷反应，形成聚酯多元醇或聚醚 - 聚酯多元醇。这两个步骤在胺催化剂和双金属氰化物络合物催化剂的存在下进行。该方法以低量的环氧乙烷作为反应物（例如，小于5重量％）提供高的伯羟基官能度（例如，高达95％，基于总功能）。

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.
摘要翻译：制备混合聚酯 - 聚醚多元醇的方法包括任选地在一种或多种双金属氰化物催化剂，超酸催化剂，超酸催化剂的金属盐和/或其中的一种或多种的存在下使含羧基的组分和环氧化物接触，或叔胺催化剂，在形成混合聚酯 - 聚醚多元醇的条件下进行。当用于聚氨酯配方时，混合聚酯 - 聚醚多元醇具有酯和醚官能团的优点，从而提高物理性能。该方法产生具有窄多分散性，低酸值和不饱和度的产物，以及减少的副产物形成，特别是当使用双金属氰化物催化剂时。

摘要： Polystyrene is dispersed into a polyol via a mechanical dispersion process. A stabilizer is present to stabilize the dispersed polymer particles. The stabilizer includes a copolymer of (1) from 10 to 70% by weight of a branched polyol which has a molecular weight of from 4000 to 20,000, from 0.2 to about 1.2 polymerizable ethylenically unsaturated groups per molecule and from about 3 to about 8 hydroxyl groups per molecule with (2) from 30 to 90% by weight of styrene or a mixture of styrene and one or more other low molecular weight monomers.
