摘　　要：以综合性能优异的烯丙基化聚苯醚(PPO)为基础树脂,采用质量分数为10%的双(3-乙基-4-马来酰亚胺基苯)甲烷(BEDM)作为烯丙基化PPO的交联剂,无引发剂热聚合得到一种均一透明的、介电常数(ε)和介电损耗角正切(tanδ)均低、玻璃化转变温度(Tg)较高、吸水率低的新型热固性PPO树脂。对烯丙基化PPO/BEDM体系的非等温固化动力学进行研究,计算得到其固化反应级数为0.95,固化反应表观活化能为160.43kJ/mol,以及频率因子和反应速率常数等数据。同时确定了该体系的固化工艺参数。BEDM改性烯丙基化PPO固化树脂的Tg为208.24℃,ε(1MHz)为2.87,tanδ(1MHz)为0.011,吸水率为0.28%,能满足高性能印制电路板用树脂的要求,具有较好的应用前景。With allylated poly（phenylene oxide）（PPO） which had well combined properties as matrix resin, bis（3-ethyl-4- maleimidophenyl） methane （BEDM）（ 10% weight of PPO） as crosslink agent, a novel unifrom and transparent thermosetting resin of PPO which had low dielectric constant （ε）, dielectric loss and water absorption, as well as high glass transition temperature （ T ） was obtained. Nonisothermal curing kinetics of the PPO resin modified with the BEDM was investigated, and the euring reaction order （n） , apparent activation energy （E）, frequency factor （A） and rate constant（k） at different heating rates were obtained,n and E were 0.95 and 160.43 kJ/mol, respectively. Curing process parameters of the BEDM/PPO resin were obtained also. Furthermore, values of the Tg ,ε（ 1 MHz） ,tangent of the dielectric loss angle （ tanδ, 1 MHz） and water absorption of the cured BEDM/PPO resin were determined to he 208.24℃ , 2.87, 0.011 and 0.28% , respectively. The BEDM/PPO resin could meet the requirements of the PCB with high performances, and it had a better prospect of application.
