Abstract

The invention discloses polyaryletherketone containing nitrile group and perfluorocyclobutyl aryl-ether structure, wherein m represents degree of polymerization, and X+Y is less than or equal to 50 and greater than or equal to 10. The invention also discloses a synthetic method of the polyaryletherketone containing nitrile group and perfluorocyclobutyl aryl-ether structure. The synthetic method comprises the following steps: placing a perfluorocyclobutyl aryl-ether polymer, dihalogenated benzonitrile or dihalogenated para-Phthalonitrile, 4,4'-difluorobenzophenone and a catalyst into a solvent, carrying out multiple temperature-control reactions, precipitating, filtering, washing and carrying out centrifugal drying to obtain a polyaryletherketone sample containing nitrile group and perfluorocyclobutyl aryl-ether structure. The prepared polyaryletherketone containing nitrile group and perfluorocyclobutyl aryl-ether structure has high temperature resistance and corrosion resistance, radiation resistance and flame retardant property, and has multiple cross-linking points.
