摘要

本研究以4-氟-3-三氟甲基苯酚作为单体、二苯砜为反应溶剂，成功合成了高分子量的含氟聚芳醚(CF

PPO). 含氟聚芳醚的数均分子量达7.74×10

Da，重均分子量达2.49×10

Da，熔点为243 ℃，玻璃化转变温度(

)为112 ℃. 同时，研究了分子量大小对含氟聚芳醚材料结晶性能的影响，高分子量的聚合物结晶较慢，需要经过热处理才能结晶. 注塑样条的拉伸强度为82 MPa，断裂伸长率为134%；经过热处理后拉伸强度增加到96 MPa，而断裂伸长率却下降到9%. 此外，由于聚合物同时具有苯环和氟原子的结构特性，结晶的聚合物薄膜的介电常数高达4.32，且聚合物薄膜在高频时具有较低的介电损耗，在10

Hz时介电损耗仅为0.0017.

Abstract

In this study

4-fluoro-3-trifluoromethylphenol was used as a monomer and diphenylsulfone was used as a reaction solvent to successfully synthesize high molecular weight fluoropolyarylene (CF

PPO). The number average molecular weight of fluoropolyarylene (CF

PPO-0.52) reached 7.74×10

weight average molecular weight reached 2.49×10

melting point was 243 ℃

and glass transition temperature (

) was 112 ℃. At the same time

this work studied the influence of molecular weight on the crystallization properties of fluoropolyarylene materials. High molecular weight polymer crystallization is slow and needs to be heat treated to crystallize. The tensile strength of the injection molded spline was 82 MPa

and the elongation of break was 134%; after heat treatment

the tensile strength increased to 96 MPa

but the elongation of break is reduced to 9%. In addition

since the polymer has both the structural characteristics of benzene ring and fluorine atoms

the dielectric constant of the crystalline polymer film is as high as 4.32

and the polymer film has a lower dielectric loss at high frequencies

and the dielectric loss at 10

Hz is only 0.0017.
