ABSTRACT:
This invention provides a method for preparing elastic polyurethanes from organic polyisocyanates and polymer-polyol mixtures, wherein the polymer is obtained by polymerizing an ethylenically unsaturated monomer in a polyol. This invention further provides a method for preparing cellular polyurethanes from organic polyisocyanates and polymer-polyol mixtures, wherein the polymer is obtained by polymerizing an ethylenically unsaturated monomer in a polyol. This invention still further provides polyurethanes produced by the aforementioned methods.
