摘要： Polycarbonate type nonionic surfactant compositions comprising monohydroxy alcohols capped with polycarbonate groups. More specifically, the surfactant compositions comprise aliphatic, nonaromatic cycloaliphatic or aromatic alcohols which have been capped with block polycarbonate groups formed by the reaction of the alcohols with ethylene carbonate in the presence of an alkali metal salt catalyst. The surfactant properties of the compositions may be varied by first reacting the alcohols with ethylene oxide to form a block polyether group cap on the alcohols before the reaction with ethylene carbonate or by further reacting the polycarbonate capped alcohols with ethylene oxide to form a terminal polyether block group. The surfactants formed are a random distribution mixture of compositions wherein 2 to 20 moles of ethylene carbonate and 3 to 50 moles of ethylene oxide per mole of the alcohols are reacted together.
摘要翻译：包含用聚碳酸酯基封端的一羟基醇的聚碳酸酯型非离子表面活性剂组合物。更具体地说，表面活性剂组合物包括脂肪族，非芳族的脂环族或芳族醇，其已经用碱金属盐催化剂存在下通过醇与碳酸亚乙酯的反应形成的嵌段聚碳酸酯基封端。组合物的表面活性剂性质可以通过首先使醇与环氧乙烷反应来改变，以在与碳酸亚乙酯反应之前在醇上形成嵌段聚醚基帽，或通过使聚碳酸酯封端的醇与环氧乙烷进一步反应形成末端聚醚嵌段组。所形成的表面活性剂是一种组合物的随机分布混合物，其中每摩尔醇将2至20摩尔碳酸亚乙酯和3至50摩尔环氧乙烷反应。
