NOVEL POLYURETHANE COMPOSITIONS INCLUDING CASTOR OIL

摘要

At least certain embodiments of the present Invention relate Io polyurethane compositions for forming a layer of polyurethane on a textile, fabric or material, such as a flooring fabric or a non-flooring fabric. The compositions comprise the reaction product of castor oil having a water content of less than or equal to about 0 2% by weight, a monol, and an isocyanate, wherein the reactants have a soft segment functionality of about 2.0 to about 264. Selected embodiments may provide compositions for use in surface coverings such as as floor coverings having a show surface such as a textile or fabric face material in contacting overlying relation to a polyurethane backing with or without additional structures, layers, backings, and/or the like.
