Latest Patents
Vrijesh holds a patent for "Castor oil derived hydroxy functional acrylic copolymers for surface coating applications." This invention involves the creation of acrylic polyols that comprise hydroxy functional acrylic copolymers or resins. These resins feature an acrylic backbone that incorporates modified castor oil sourced hydroxyl functionalities. The synthesis process involves co-reacting modified hydroxy functional castor oil with various acrylic monomers, styrene or its derivatives, and optionally hydroxyalkyl acrylates/methacrylates and ethylenic monomers through solution polymerization in the presence of an initiator. The hydroxyl functionality is imparted solely or partially through renewable castor oil, with the resins synthesized at up to 100% solids and hydroxyl values ranging from 25-150 (mg KOH/gm). When cured with suitable polyisocyanates or amino resin cross-linkers, these synthesized resins provide tough, glossy, and chemical and weather-resistant coatings.
