In the present study, an acid-functional acrylic copolymer has been synthesized using butyl methacrylate and maleic anhydride. In addition, the hydroxyl ethyl fatty amide of castor oil has also been synthesized and used as a curing agent for the acid-functional acrylic copolymer to form polyesteramide resins. The effect of crosslinking agent on the acrylic copolymers was examined. A series of coating compositions with varying amounts of acrylic copolymer and hydroxyl ethyl fatty amide were prepared, and their mechanical, optical and chemical resistance properties studied.
