| Abstract: | The effects of process conditions on product property were studied in the synthesis ofDCPD-modified unsaturated polyester by blocking of terminal groups.The results show thatthe optimal conditions of synthesis reaction are as follows:the total anhydride/propyleneglycol/DCPD ratio is l :1.1:0.1-0.16,and when acid value is 50 mgKOH·g￣(-1) with gradualaddition of DCPD,the addition time is l-2h,reaction time is about 2h. |
