A novel tri-functional castor oil-based methacrylate prepolymer (MCOG) was developed by mercapto castor oil (MCO) and glycidyl methacrylate (GMA) in this study through a two-step method. Primarily, the mercapto castor oil (MCO) was prepared through thiol-ene reaction of castor oil and mercaptoacetic acid, and subsequently an esterification reaction based on above product and glycidyl methacrylate (GMA) was conducted.
