摘要： 研究了苯乙烯(St)、聚醚砜双烯大分子单体(PES-3-MA)、甲基丙烯酸铅[Pb(MA)2]、桂皮酸钡[Ba(CA)2]等多元共聚透明树脂的结构与性能的关系。实验结果表明:随PES-3-MA及Pb(MA)2含量的增加,树脂的线膨胀系数α下降,树脂的密度却增大;间接求得D20(4P(PES-3-MA)=1.330、D20(4P(PSU-3-MA)=1.200、D20(4P[Pb(MA)2]=2.100;PES-3-MA含量增加,树脂的硬度增大;Pb(MA)2量增加,硬度下降;耐热性与不含Pb(MA)2相比提高30～40℃。光声光谱研究表明悬吊双键需经较高温度的热处理才能进一步反应完全。

Abstract: In this paper, transparent resin——copolymer of styrene, bisvinyl poly (ether-sul-fone)s macromonomer(PES-3-MA), Pb(MA)2, Ba (CA)2 was synthesized, and the relation between structure and properties of the multicomponent transparent resin was studied.The experimental results indicate that with the increases of PES-3-MAor Pb(MA)2 ratio, the density of the resin will increase, the linear expansion coefficient a will decrease to 50～70×10-6℃-1, Tg arise to 140℃.It was obtained that D204p(PES-3-MA)=1.33, D204p[Pb(MA)2]=2.10.This is consistent with the calculated value.Studies by FTIRshow that if one wants pendant vinyl bond to react completely, high temperature heat treatment is needed.
