摘要： Polyoxyalkylene polyether polyols suitable for preparation of flexible polyurethane foams are prepared by oxyalkylating an aqueous solution of one or more polyhydric, hydroxyl-functional solid initiators under conditions where both water as well as initiator are oxyalkylated. The polyols have calculated functionalities of between about 2.2 and 4.0 and hydroxyl numbers in the range of 10 to 180. The polyols may be used to prepare soft, high resiliency polyurethane flexible foams at low isocyanate indexes.
摘要翻译： 适用于制备柔性聚氨酯泡沫的聚氧化烯聚醚多元醇通过在水和引发剂均为烷氧基化的条件下将一种或多种多羟基羟基官能的固体引发剂的水溶液进行烷氧基化来制备。 多元醇具有约2.2至4.0之间的官能度，并且羟基数在10至180的范围内。多元醇可用于在低异氰酸酯指数下制备柔软的高弹性聚氨酯柔性泡沫。
