摘要
以2，6-二氯苯甲腈（DCBN）和4，4-二羟基二苯砜（DHDPS）为原料，通过常压溶液缩聚合成了一种耐高温的无定形聚芳醚腈砜（PENS）。用FT—IR，DSC，TG等手段对PENS聚合物的结构和热性能进行了研究，同时表征了PENS薄膜的介电性能。结果表明：PENS具有很高的玻璃化转变温度（215．4℃），5％热失重温度为453℃。PENS具有很好的介电性能，其介电常数为3．6—4．1F／m，在玻璃化转变温度前具有很好的介电稳定性。
Poly （ arylene ether nitrile sulfone） （PENS） was synthesized by the polycondensation with 4, 4 - dihydroxy-diphenyl sulfone（DHDPS） and 2, 6 - dichlorobenzonitrile （DCBN） as raw materials. The structure and thermal properties of PENS composite were studied by FT-IR, DSC, TG and other means. Meanwhile the dielectric property was characterized. The results showed that the PENS had high glass transition temperature which was 215.4 ℃, the temperatures for 5% weight loss was 453 ℃. The dielectric properties of PENS were great and the dielectric constants were in the range of 3.6 - 4. 1 F/m with good dielectric stability before glass transition temperature.
