| Abstract: | The Kinetics parameters of condensation polymerization reaction of maleic anhydride and phthalic anhydride respectively with that of ethylene glycol and of the Diels-Alder addition reaction of maleic anhydride and rosin have been deter- mined. The result affirmed that they are all in a secondorder reaction. The reaction rate constants and the macroscopic activation energy at different temperatures were found. The optimal technological conditions for the sythesis of rosin-modified unsaturated polyesters resin of the best behavior were provided. |
