Abstract

Abstract

DCPD-type unsaturated polyester resin prepared by using semi-condensation polymerization method is proposed. The results show that the optimal conditions of synthesis reaction are as follows:the total anhydride/propylene glycol/DCPD ratio is 11.10.10～0.15～0.15, temperature of addition reactions is 120-140℃，acid value of system is 120-140mg KOH/g when dropping DCPD and time of addition reaction is about 2h.
