摘要： Ethylene carbonate is polymerized by itself or together with another cyclic monomer such as 1,2-propylene oxide in the presence of a double metal cyanide catalyst. Most of the ethylene carbonate adds to the chain to form a terminal carbonate group, which decarboxylates to produce a hydroxyethyl group at the end of the polymer chain. The polymerization of more ethylene carbonate onto the chain end results in the formation of poly(ethyleneoxy) units. Therefore, the process provides a method for making poly(ethyleneoxy) polymers without the need to polymerize ethylene oxide. The process is useful for making polyethers that are useful as water-absorbable polymers, surfactants and as raw materials for polyurethanes. The process is also useful for increasing the primary hydroxyl content of a polyether.

摘要翻译： 在双金属氰化物催化剂存在下，碳酸亚丙酯本身或其它环状单体如1,2-环氧丙烷聚合。 大多数碳酸亚乙酯添加到链上以形成末端碳酸酯基团，其在聚合物链末端脱羧以产生羟乙基。 更多的碳酸亚乙酯在链末端的聚合导致聚（乙烯氧基）单元的形成。 因此，该方法提供了制备聚（乙烯氧基）聚合物而不需要聚合环氧乙烷的方法。 该方法可用于制备可用作吸水聚合物，表面活性剂和聚氨酯原料的聚醚。 该方法也可用于增加聚醚的伯羟基含量。

摘要： A polyglycerine initiated polyether polyol exhibiting a final functionality less than the nominal functionalities of the polyol initiator wherein the initiator is a polyglycerine formed by the polymerization of glycerin having an HEW less than about 35 and exhibiting a nominal functionality between 2 and 16 is provided. Also provided is a process for producing a polyfunctional polyurethane by the reaction of a mixture containing a polyol based on polyglycerine initiator wherein between 5 wt % and 100 wt % of the total initiator is polyglycerine having a nominal functionality between 2 and 16, at least one organic isocyanate, an amine and/or a metal salt catalyst, and optionally a blowing agent. Also provided is a flexible polyurethane foam comprising a reaction product of a polyglycerine or formed by the glycidol polymerization of glycerin, at least one organic isocyanate, and an amine catalyst.
