A process for preparing a fluorinated poly(arylene ether) comprising the repeating unit:
1
wherein n provides a molecular weight up to about 30,000 to 100,000, X represents one of following groups: none, ketone, sulfone, sulfide, ether, hexafluoroisopropylidene, &agr;&ohgr;-perfluoroalkylene, oxadiazole, and Y is 4,4′-(hexafluoroisopropylidene)-diphenyl, 4,4′-isopropylidene diphenyl, 3,3′-isopropylidene diphenyl, phenyl, or chlorinated phenol which process comprises reacting a bis(pentafluorophenyl) compound and a bisphenol or hydroquinone in the presence of a dehydrating agent and a polar aprotic solvent is disclosed. Polymers resulting from the process show good promise as new passive optic polymer waveguide materials.
一种包含重复单元的氟化聚芳基醚的制备工艺:
1
其中 n 的分子量最高约为 30,000 至 100,000,X 代表下列基团之一:无、酮、砜、硫醚、醚、六氟异亚丙基、&agr;&ohgr;-Y 是 4,4′-(六氟异亚丙基)-二苯基、4,4′-异亚丙基二苯基、3,3′-异亚丙基二苯基、苯基、或氯化苯酚,其工艺包括在脱水剂和极性非烷基溶剂存在下,使双(五氟苯基)化合物和双酚或对苯二酚发生反应。该工艺产生的聚合物有望成为新型无源光学聚合物波导材料。
