将耐高温可溶解的杂萘联苯共聚芳醚砜（PPBES）与聚芳醚腈酮（PPENK）共混，采用溶液浸渍法制备了玻纤布增强PPBES/PPENK树脂基层压板。研究了树脂的相容性及树脂配比以及共混树脂含量对PPBES/PPENK层压板的室温及150℃弯曲强度、吸水率的影响，对层压板的介电性能、阻燃性能等进行了测试。结果表明：PPBES与PPENK完全相容。当PPBES/PPENK=4/6（质量比），树脂含量为35.4%时，层压板的综合性能最佳，且150℃的弯曲强度保持率为90.4%。在1MHz下，介电常数为3.5，tanδ为0.0037；在DC500V下，体积电阻率为5.9×1013Ω· m；阻燃性能达到V-0级。

The PPBES/PPENK laminate is prepared through the blend of poly(phthalazinone biphe-nylene ether sulfone) (PPBES) and poly(phthalazinone ether nitrile ketone) (PPENK) which have thermostabil-ity and reasonable solubility by solution dipping process. The compatibility and ratio of resins are discussed. The effects of PPBES/PPENK resin content on the flexural strength at 25℃and 150℃, respectively, and water abso-rption of the laminate are studied. The dielectric properties and lfame retardancy of the laminate are tested. The SEM result approves that PPBES and PPENK are fully compat-ible. The results show that the laminate has optimum comprehensive performance when the blending resin with the ratio of PPBES/PPENK=4/6 content is 35.4%. Under condition of 1MHz, the dielectric constant and dielectric loss are 3.5 and 0.0037, respectively. The volume resistiv-ity is 5.9×1013Ω·m at DC500V. Its lfame retardant property rate is UL94-V0.
