Abstract
High viscosity or solid resins containing hydroxyl groups can be modified by esterification with ricinoleic acid to yield polyols having much lower viscosity, improved solubility in non-polar solvents, higher equivalent weights and essentially the same hydroxyl functionality of the unmodified resin. These new polyols or their mixture with other polyols can be reacted with solventless polyisocyanates to yield polyurethane compositions useful as adhesives, potting or molding compounds. Alternatively, they can be diluted with a small amount of appropriate solvents and reacted with polyisocyanate, melamine or urea-formaldehyde resins, or used in the preparation of alkyd resins, yield high solids coatings useful in a variety of applications, such as plastics, business machine parts, metals, wood and building materials such as concrete, bricks, cinder blocks and the like.
