Abstract

The copolymerization of epoxy (1,4-butanediol diglycidyl ether (DGEBA) with anhydride (cis-l,2-cyclohexanedicarboxylic anhydride (CH) in the presence of benzyl dimethyl amine (CA) as a catalyst produces a branched epoxy polymer. We show that the branching kinetics of the copolymerization reaction and the molecular weight of the branched polymers formed during the copolymerization reaction before the gelation threshold can be approximated by using Smoluchowski’s coagulation equation.
