Abstract

The invention relates to reactive polyarylene ether nitrile imide resin and a preparation method thereof, and belongs to the technical field of high polymer materials. The molecular structural formula of the reactive polyarylene ether nitrile imide resin is as following. The preparation method includes: (1) adding amino-terminated polyarylene ether nitrile oligomer, tetracid dianhydride compounds and polar aprotic solvent into a reaction kettle for reaction at the temperature of 0-60 DEG C for 2-4 hours; then adding monofunctional unsaturated cyclic organic acid anhydride for reaction for 3-6 hours to generate an amic acid intermediate; (2) heating up a reaction system containing the amic acid intermediate to 40-80 DEG C, adding catalyst and dehydrant, and performing imide cyclization reaction for 4-8 hours; performing precipitation and filtration drying to obtain the reactive polyarylene ether nitrile imide resin. The prepared resin has good solubility, is excellent in mechanical property and heat resistance in cured materials, and has broad prospect in aerospace and electronic information fields; the preparation method has the advantages of simplicity and easiness in control.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and particularly relates to a reactive polyarylether nitrile imide resin and a preparation method thereof. Background technique [0002] Polyimide resin (PI) is a kind of polymer material that contains imide ring in the main chain and has excellent comprehensive properties. With outstanding temperature resistance, mechanical properties, dielectric properties and radiation resistance, it has been widely used in the fields of high temperature resistant polymer-based composite materials, microelectronic packaging and coating materials. [0003] According to thermal properties, it can be divided into thermoplastic and thermosetting polyimide. Due to the poor solubility of traditional aromatic thermoplastic PI resins, the precursor polyamic acid solution is generally used to prepare prepregs, and then imide cyclization is carried out at high temperatures to prepare PI-based composites. Due to the...
