Abstract

The invention discloses a poly(aryl ether ketone) cable material resin and a synthesis method thereof. According to the synthesis method, perfluorocyclobutylaryl ether-phenol polymer, hexafluorobisphenol A, dihalobenzonitrile / dihalo-para-phthalonitrile, and 4,4'-difluorobenzophenone are taken as the raw materials; and after two temperature controlled reactions in a nitrogen atmosphere in the presence of a catalyst, the reaction product is subjected to precipitation, filtration, washing, and centrifugal drying to obtain the poly(aryl ether ketone) cable material resin. The thermal stability, crystallinity, and dissolvability of the polymer are effectively improved; the polymer dielectric constant, polymer dielectric loss factor, and signal attenuation ratio of high speed transmission frequency band are reduced; at the same time, the excellent properties of poly(aryl ether ketone) material are preserved; and the poly(aryl ether ketone) material has the advantages of poly(arylene ether nitrile), polyether ether ketone, and a material having a fluorine containing structure.

Description

technical field [0001] The invention relates to a polyaryl ether ketone cable material resin and a synthesis method thereof, belonging to the field of polymer materials. Background technique [0002] Polyaryletherketone is an aromatic thermoplastic special engineering plastic with good physical and chemical properties, so it is often used as a cable material. However, it is difficult to form a uniform blend between traditional polyaryletherketone polymers, and the requirements for the preparation process are relatively complicated, and more additives are added, which undoubtedly increases the product cost and reduces the reliability of the cable. In recent years, focusing on improving the processing performance and improving the heat resistance level, such new materials with excellent performance have been continuously developed to meet different use requirements. For example, different functional groups are introduced into the polymer main chain, such as naphthalene rings,...
