| 摘 要： | 采用环氧丙烯酸酯 (VE)为间苯二甲酸二烯丙酯 (DAIP)树脂的增韧剂 ,体系的韧性得到改善。利用 DSC、FTIR等方法进一步研究了 DAIP/ VE体系的聚合反应 ,证明改性体系中存在两个反应阶段 ;前一阶段即低温固化阶段 ,主要为 VE与 DAIP的共聚反应以及少量 VE的自聚反应 ;后一阶段即高温固化阶段 ,主要为 DAIP的自聚反应。改性体系与未改性体系相比 ,断面形态结构更为多样。

| Abstract: | When VE is used to tough DAIP resin,mechanical properties such as impact strength of the resin is improved.DSC,FTIR and SEM are employed to characterize DAIP/VE resins.DSC and FTIR Prove that there are two stages in curing process of DAIP/VE.The first is DAIP/VE copolymerization and VE self polymerization,and the second is DAIP self polymerization. Due to the copolymerization of DAIP and VE,the modified resins have more irregular structures and lower crosslink densities,which make an increase in toughness.SEM show a more complicate structure of the modified resin. |
