摘 要:首次将两种高性能印制电路板(PCB)用树脂——聚苯醚(PPO)和多马来酰亚胺(PMI)相结合,以烯丙基化PPO为基础树脂,采用质量为PPO的10%的3,3′-二乙基-4,4′-二苯甲烷型多马来酰亚胺(PEDM)作为交联剂,无引发剂热聚合得到一种新型热固性PPO树脂。PEDM改性烯丙基化PPO固化树脂的Tg为204.71℃,介电常数(,ε1 MHz)为2.69,介电损耗角正切(tanδ,1 MHz)为0.0032,吸水率为0.21%,能满足高性能PCB用树脂的要求。同时,对PEDM/烯丙基化PPO体系的非等温固化动力学进行了研究,并确定了该体系的固化工艺参数。As major resins of printed circuit board (PCB) with high performances, poly(phenylene oxide) (PPO) and polymaleimide (PMI) were first combined in this study. With weight of 10% of the PPO, a polymaleimide of bis(3-ethyl-4-maleimidophenyl) methane type (PEDM) was utilized as crosslink agent of the allylated PPO resin. By a thermopolymerization without initiating agent, a novel uniform and transparent thermosetting resin of PPO was obtained. Values of Tg, dielectric constant (ε,1MHz), the dielectric loss tangent (tang, 1MHz) and water absorption of the cured PEDM/ PPO resin are determined to be 204.71℃, 2.69, 0.0032 and 0.21% ,respectively, which can meet the requirements of the PCB with high performances. Furthermore, values of curing reaction order (n) and apparent activation energy (Ea) of the PEDM/PPO resin were calculated to be 0.95 and 170.60 kJ/mol, respectively. Curing process parameters of the PEDM/PPO resin were obtained also.
