摘要： Acrylic polyols comprising hydroxy functional acrylic copolymers/resin involving an acrylic backbone having modified castor oil sourced hydroxyl functionalities and synthesized by co-reacting modified hydroxy functional Castor Oil with variety of acrylic monomers, styrene or its derivatives and optionally hydroxyalkyl acrylates/methacrylates and ethylenic monomer through solution polymerization in presence of an initiator. The hydroxyl functionality is solely or partially imparted through renewable Castor Oil wherein the resins were synthesized at upto 100% solids and at hydroxyl values ranging from 25-150 (mg KOH/gm). The synthesized resins when cured with suitable polyisocyanates or amino resin cross-linkers provided tough, glossy and chemical & weather resistant coatings.
