Unsaturated polyester prepolymer was synthesized from maleopimaric acid (MPA), diethylene glycol (DEG) and maleic anhydride (MA) in the molar proportions 1 : 4:3 respectively. MPA was prepared from natural rosin and MA. Kinetic studies of the reaction were performed, and the reactivities of MPA, MA

Based on the structural model being derived in Part I, a statistics approach has been used to further estimate separately carboxyl and hydroxyl functionalities of unsaturated polyester (UP) prepolymers directly from their molecular parameters. This extended model shows satisfactory results when comp
