ABSTRACT:
A modified polyurethane structionally incorporating filler having active hydrogen groups on a surface thereof into a polyurethane polymer. The filler is first fluidized with a polyol and then reacted with a linking component having an organo reactive group that is reactive with an isocyanate. Polyisocyanate and additional polyol are added to the reaction mixture such that the isocyanate reacts with the linking component and the polyol to form a polymer wherein the filler is an integral unit in the polymer. The resultant modified polyurethane has good dynamic properties and is surprisingly resilient. Preferred fillers are sand, clay talc and mixtures thereof.
