POLYMER-MODIFIED POLYOL DISPERSIONS AND PROCESSES FOR PRODUCTION AND USE THEREOF

摘要

A polymer-modified polyol dispersion comprises a polyaddition product dispersed in a polyol. The polyaddition product is present in an amount of from about 25 to about 70 percent by weight based on the total weight of the polyaddition product and the polyol. The dispersion has a viscosity in the range of from about 4,000 to about 50,000 mPa. s, the viscosity remaining substantially the same after production of the dispersion. A process for producing the polymer-modified polyol dispersion is also disclosed together with a process for using the dispersion to produce a polyurethane foam.
