摘要： Linear polypropylene ether glycols of high molecular weight are made by reacting a linear polypropylene ether glycol of lower molecular weight first with an alkaline agent such as sodium hydroxide or other suitable base to form an alcoholate, and then coupling the alcoholate with a suitable difunctional coupling agent, such as the benzene-sulfonic acid diester of ethylene glycol or with some other suitable arylsulfonic acid diester of a C.sub.2 to C.sub.6 alcohol, thereby obtaining a 100 percent linear polypropylene ether glycol of a desirably higher molecular weight. Materials so produced find use in an aqueous medium as defoaming agents, thickeners, or emulsifiers, and use as protective colloids to improve the low-temperature stability of polyurethane and other latices.
摘要翻译： 通过使低分子量的线性聚丙烯醚二醇与碱性试剂如氢氧化钠或其它合适的碱反应形成醇化物，然后将醇化物与合适的双官能偶联剂 ，例如乙二醇的苯磺酸二酯或与C 2至C 6醇的一些其它合适的芳基磺酸二酯，从而获得理想的较高分子量的100％线性聚丙烯醚二醇。 如此制造的材料在水性介质中用作消泡剂，增稠剂或乳化剂，并且用作保护胶体以改善聚氨酯和其它胶乳的低温稳定性。

摘要： New polyether polyols of predetermined structure are prepared by reacting polyether bis alcoholates with selected bis epoxides. Specifically, a polyoxyalkylene glycol is converted to the bis alcoholate, and then the bis alcoholate is reacted with an equivalent amount of a glycol bis glycidyl ether, with the reactants being mixed together all at once. The polyether polyalcoholate thus obtained is converted to a high molecular weight polyether polyol by acid neutralization or ion exchange.
