| 摘 要： | 近年来，随着对高分子材料功能化研究的深入，合成了许多具有特殊性能的聚芳醚酮．聚芳醚酮是一类综合性能优异的半结晶性特种工程塑料，在分子链中引入氟官能团可降低聚合物的介电常数．然而，不对称强极性氟的引入增加了聚合物分子的极性，不利于进一步降低介电常数，且在高温加工时容易放出氟化氢．因此，无氟、低氟的低介电高分子材料将会有很好的发展前景．

| Abstract: | A novel monomer [2-(4-phenoxyphenyl)-1,4-diphenol] was synthesized. A novel polymer(4-phenoxyphenyl)PAEK was successfully synthesized with this new type of diphenol and 4,4'-difluorobenzophenone in TMSO. The 1H NMR and IR characterizations of the monomer and polymer were described. Some properties of the polymer were also given out. It keeps good properties of PEEK(poly ether ether ketone)(Tg is 407 K and TGA plot shows that the weight loss of the monomer is 5% at 320 ℃ and 10% at 347 ℃) and also has better solubility, lower dielectric constant 2.9 at 1 MHz and lower dielectric loss 4.49×10-3 at 1MHz. This kind of novel non-fluorinated PAEK(poly aryl ether ketone) with anisomerous big side group is very promising for electronic applications |
