Abstract
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.
Claims19
Polymer polyols with a high solids content made by the reaction of at least one alkanolamine with at least one organic polyisocyanate in a polymer polyol as a dispersing media.
Polymer polyols with a high solids content made by the reaction of at least one alkanolamine with at least one organic polyisocyanate in a polymer polyol as a dispersing media, wherein the ratio of equivalents of alkanolamine groups to equivalents of isocyanate groups ranges from 1 to 5, to give a mixture of polymer polyols with a solids content in the range between about 20 and about 50%.
A method for producing polymer polyols having a high solids content comprising reacting at least one alkanolamine with at least one organic polyisocyanate in a polymer polyol as a dispersing media.
