Polymerization and Properties of Diethylene Glycol Bis(allyi carbonate)

The prepolymerization and the curing reaction of diethylene glycol bis(allyl carbonate) in the presence of initiator were investigated; the regression equations and rate constant of the prepolymerization under different conditions were determined, and the curing reaction process were analysed by means of DSC and FTIR. The results show that the reaction temperature and the amount of initiator are the main influencing factors on the prepolymerization, the prepolymerization activation energy is 133 kJ/mol, and the curing reaction activation energy is 93.6 kJ/mol, DADC resin and its composites possess better comprehensive properties.
