Abstract

The invention relates to a hyperbranched poly (ether ketone), a preparation method thereof and application of the material in viscosity modifiers. The hyperbranched poly(ether ketone) is prepared wit BB2-type monomers 2, 4, 6 trifluoro phenyl ketone and A2-type monomers hydroquinone, resorcin, bisphenol A, and hexafluoro-bisphenol A or biphenyl diphenol as reactants, potassium carbonate or sodium carbonate or the mixture of the potassium carbonate and the sodium carbonate as a salification agent, and sulfolane or N, N-dimethyl ketopyrrolidine as a solvent through mixing, salification, polycondensation reaction and after treatment. The solid content is 20 to 30 percent; the dosage of the salification agent is 1 to 1.1 time of the dosage of the A2 monomers. Fluorine terminated hyperbranched polyaryletherketone and hydroxy terminated superbranched polyaryletherketone are got respectively by adjusting the ratio of the dosages of the BB2-type and A2-type monomers. The hyperbranched poly (ether ketone) is characterized in that by adding the superbranched polyaryletherketone, the mechanical property and the thermostability of linear polyaryletherketone are not reduced while the melt viscosity of the linear polyaryletherketone is reduced.
