摘要： A method of forming a polyol includes the steps of reacting an initiator with an alkylene oxide, and optionally carbon dioxide, in the presence of a double metal cyanide catalyst and a sterically hindered chain transfer agent capable of protonating the growing polyol polymer. The presence of the chain transfer agent reduces the polydispersity of the resultant polyol.

摘要： A resin composition includes a polyol and is used to form flexible foams. The resin composition also includes water and an alkoxylate of an active hydrogen containing species. The alkoxylate of the active hydrogen containing species acts in two separate ways. The alkoxylate acts as a blowing reaction modifier, thus maintaining slow-blow behavior of a foaming process that accompanies a reaction of the polyol with an isocyanate. The alkoxylate also acts as a compatibilizer. As the compatibilizer, the alkoxylate stabilizes the resin composition such that no phase separation occurs between the polyol, the water, and the alkoxylate. Stabilizing the resin composition allows for multiple day storage of the resin composition with no phase separation, thus extending useable shelf life and reducing production costs. Stabilizing the resin composition also allows for formation of flexible foams with consistent physical properties such as flexibility.
摘要翻译： 树脂组合物包括多元醇并用于形成柔性泡沫。 树脂组合物还包括含有活性氢的物质的水和烷氧基化物。 含活性氢物质的烷氧基化物以两种分开的方式起作用。 烷氧基化物起到吹塑反应改性剂的作用，因此保持伴随多元醇与异氰酸酯反应的发泡方法的缓慢吹塑性能。 烷氧基化物也起增容剂的作用。 作为增容剂，烷氧基化物稳定树脂组合物，使得多元醇，水和烷氧基化物之间不发生相分离。 使树脂组合物稳定化可以使树脂组合物在不相分离的情况下多天储存，从而延长了可用的保质期并降低了生产成本。 稳定树脂组合物还允许形成具有一致的物理性质如柔性的柔性泡沫。
