含双酚-A和杂环结构的聚芳醚酮的合成与表征

Synthesis and Characterization of Poly(aryl ether ketone) from 4-(4-Hydroxyphenyl)-2,3-phthazin-1-one, Bisphenol-A and 4,4′-Difluorobenzophenone

用苯酚、苯酐和水合肼合成了 4 ( 4 羟苯基 ) 2 ,3 二氮杂萘酮 1,并与双酚 A和二氟二苯甲酮聚合 ,得到含双酚 A和杂环结构的聚醚酮聚合物。用FT IR、13C NMR、DSC、TGA和DMA等方法对聚合物进行了表征。结果表明 ,这种可溶性的非晶态聚合物有较高的Tg 和很高的耐热温度 ,Tg 随聚合物的组成不同而变化 ( 15 8～ 2 2 4℃ ) ,5 %热失重温度为 4 4 4～ 5 4 1℃。

A novel poly(aryl ether keton), P(DHPZ/BP A/BFK) was prepared from 4 (4 hydroxyphenyl) 2,3 phthazin 1 one(DHPZ), bisphenol A(BP A) and 4,4′ difluorobenzophenone(BFK) monomers. Polymers were studied by FT IR, 1H NMR, 13 C NMR, DSC, TGA and DMA. It is shown that poly(aryl ether keton)s obtained are amorphous polymer with high T g, and can be soluble in most ordinary solvents. According to polymer composition, T g was 158-224?℃, 5% weight loss temperature was 444-541?℃.
