Polymer polyols with high solids content.

摘要

Polymer polyols with high polymer or solids content made by the reaction of alkanolamines with polyisocyanates in a dispersing media of polymer polyols created from vinyl monomers in a conventional manner. The equivalents of alkanolamine to equivalents of polyisocyanate ranges from about 1/1 to 5/1 to give novel polymer polyols with solid contents from about 25% to up to 50%. Polyurethane foams made employing the novel polymer polyols of the present invention have higher load bearing properties, and provide a good balance between the load bearing properties and the open cell content of the foam to provide a stable foam, as compared with those employing only conventional polymer polyols.
