以1，4-二乙烯基全氟丁烷和1，6-二乙烯基全氟己烷与芳烃单体进行Mizoroki-Heck共聚反应，合成了主链上含有全氟亚烷基[-(CF2)n-，n=4，6]、乙烯和亚芳基的半氟化芳香聚合物。无配体Pd(OAc)2/Bu4NBr体系(“Jeffrey条件”)催化1，4-二乙烯基全氟丁烷和1，4-二碘苯的共聚反应，而Herrmann型杂环络合物(“Herrmann‘s催化剂”)有效地催化了二溴代芳烃单体(如1，4-二溴苯)的共聚。所合成的半氟芳烃聚合物的数均相对分子质量(Mn)为2.3×10~3~5.4×10~3，重均相对分子质量(Mw)为3.7~1.1×10~4。这些聚合物表现出很高的热稳定性，其5%的失重温度(TD5%至415℃)表明。
Semi-fluorinated aromatic polymers containing perfluoroalkylene [-(CF2)n-,n= 4, 6], vinylene, and arylene units in their main chains were synthesized via the Mizoroki-Heck co-polymerization of 1,4-divinylperfluorobutane and 1,6-divinylperfluorohexane with arylene monomers. The co-polymerization of 1,4-divinylperfluorobutane and 1,4-diiodobenzene was catalyzed by a ligand-less Pd(OAc)2/Bu4NBr system (“Jeffrey conditions”), while a Herrmann-type palladacycle complex (“Herrmann's catalyst”) effectively catalyzed the co-polymerization of dibrominated arylene monomers (such as 1,4-dibromobenzene). The number-average molecular weights (Mn) and weight-average molecular weights (Mw) values of the synthesized semi-fluorinated aromatic polymers were in the ranges of 2.3 × 103to 5.4 × 103and 3.7 × 103to 1.1 × 104, respectively. These polymers exhibited high thermal stability, as indicated by their 5% weight loss temperatures (Td5%up to 415 °C).
