  Fluid, stable polymer-polyols are provided which consist of an organic polyol medium and an interpolymer of a minor amount of polymerized ethylenically unsaturated dicarboxylic acid anhydride, such as maleic acid anhydride, and a major amount of at least one different polymerized ethylenically unsaturated monomer, the interpolymer being in the form of particles that are stably dispersed in the polyol. Polyurethane foams produced from these polymer/ polyols display improved load bearing and compression set when compared with polymer/polyols produced in a similar manner without the ethylenically unsaturated dicarboxylic acid anhydride: elastomers so produced have improved tensile modulus and tear properties.

  提供了流体稳定聚合物多元醇，它由有机多元醇介质和少量聚合乙烯基不饱和二羧酸酐（如马来酸酐）与大量至少一种不同的聚合乙烯基不饱和单体的互聚物组成，互聚物呈颗粒状稳定地分散在多元醇中。与不含乙烯基不饱和二羧酸酐的聚合物/多元醇相比，用这些聚合物/多元醇生产的聚氨酯泡沫塑料的承载能力和压缩永久变形都有所改善：用这种方法生产的弹性体具有更好的拉伸模量和撕裂性能。

  This invention relates to normally liquid, stable polymer/ polyol compositions formed by polymerizing, in the presence of a free radical catalyst, an ethylenically unsaturated monomer or monomers dissolved or dispersed in a polyol mixture including a coupled polyol consisting of the reaction product of a polyol having a functionality in excess of 2 reacted with a polyisocyanate in such proportion that the ratio of hydroxyl groups to isocyanato groups is greater than 1. In one embodiment, the coupled polyol is made in situ in the base polyol by addition thereto of the required amount of the polyisocyanate. The novel polymer/polyol compositions are convertible to polyurethane foams and elastomers.
