Abstract
Abstract Graft polyols comprising the liquid reaction product of a vegetable oil or unsaturated fatty carbon compound having at least eight carbon atoms, at least one hydroxyl group, and at least one double bond, a cyclopentadienyl compound and a terminally unsaturated monomer having at least one hydroxyl group. These liquid low viscosity polyols when cured with a polyisocyanate, melamine, or formaldehyde compound yield high solids or solventless polyurenthane compositions useful as coatings, adhesives, potting or molding compounds.
