Disclosed is a polyurethane foam and a method of preparing the same which utilizes only bio-renewable polyols and no petroleum derived polyols. The polyol is derived from a bio-renewable source and has a bio-renewable content of at least 70% by weight. The produced foams have mechanical and performance properties that are equal to or exceed those of similar polyurethane foams produced using petroleum derived polyols. The foams are preferably formed into sponges and other cleaning products for use by consumers and in industrial settings.

The present invention relates to a UV coating composition, and more particularly, to an environmentally friendly biomaterial-based UV coating composition having physical properties equal or superior to those of conventional petrochemical-based UV coating compositions.

What is described is a polymer which is a polyurethane polymer having blocked isocyanate groups or a reaction product of said polyurethane polymer with at least one epoxy resin, where the polyurethane polymer having blocked isocyanate groups is an addition product formed from at least one polyisocyanate and at least one polyester polyol, wherein the isocyanate groups of the addition product have been blocked by reaction with at least one aromatic compound having at least one hydroxyl group.
