Embodiment Construction

[0008] The specific synthetic method of the present invention is to use the bisphenol-like monomer containing phthalazinone biphenyl structure, 2,6-dihalobenzonitrile and dihalobenzophenone as raw materials, in a polar solvent, with alkali metal Or alkaline earth metal salts are used as catalysts, polymerized at high temperature, and azeotropic dehydration is carried out during the reaction. After the reaction is completed, the polymer is precipitated with a precipitant under stirring, separated, washed, and dried to obtain the polymer.

[0009] It is characterized in that the polymer molecular chain contains the following structural units:

[0010]

[0011] In the formula, R1, R2, R3, R4 can be alkyl, phenyl, hydrogen atom or halogen atom.

[0012] The bisphenol-like monomer used in the present invention contains a phthalazinone biphenyl structure, also known as a phthalazinone biphenyl (DHPZ) monomer. Its structural general formula is:

[0013]

[0014] In the formul...

Abstract

A polyarylether nitrileone containing diazanaphthalenone dibenzene structure is prepared from dihalophenyl methylnitrile, biphenol containing diazanaphthalenone bibenzene structure and dihalodiphenyl ketone through high-temp polymerizing in non-protonic polar solvent under existance of catalyst which is the salt of alkali metal or alkali-earth metal. Its advantages are high molecular weight, high toughness and strength, high resistance to high temp, and excellent electric performance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to high-performance engineering plastics synthesis technology, in particular to a polyarylether nitrile ketone containing a phthalazinone-biphenyl structure and a preparation method thereof. Background technique [0002] Polyarylether nitrile is a new class of polyarylether high-performance engineering plastics successfully developed in recent years. In 1986, the European patent EP0192177 and [Journal of Polymer Science. Part A; Polymer Chemistry 31, 3439 (1993)] filed by S. Matsuo et al. of Idemitsu Kosan Co., Ltd. disclosed a series of synthesis techniques of polyarylene ether nitriles. Chinese CN1124754A and CN1238347A also disclose the synthesis technology of two new polyarylether nitrile sulfones. [0003] Chinese invention patents ZL93109180.2 and ZL93109179.9 disclose several new high-temperature-resistant polyarylether resins, which relate to the synthesis and use o...
