Abstract

The invention discloses a phthalonitrile monomer containing a parylene structure, a phthalonitrile resin and a preparation method thereof, and the phthalonitrile monomer containing a parylene structure is obtained by taking a parylene structure-containing phenolic compound and nitrophthalonitrile as raw materials and reacting under the action of a basic catalyst. The phthalonitrile resin containing parylene is obtained through stepped heating curing reaction on the phthalonitrile monomer containing the parylene structure. According to the invention, the parylene structure is introduced into the phthalonitrile structure for the first time, and the prepared phthalonitrile monomer containing the parylene structure is reduced in melting point, has an autocatalysis effect, can be used as a curing agent for curing a traditional phthalonitrile monomer, is also a derivative monomer of the parylene structure, and can be subjected to hot processing molding; and the processing difficulty and the processing cost are greatly reduced.

Description

technical field

[0001] The invention belongs to the technical field of phthalonitrile resins, and relates to a phthalonitrile monomer, a phthalonitrile resin and a preparation method thereof. Background technique

[0002] As a high-performance thermosetting resin, phthalonitrile resin was first developed by the US Navy Experimental Base. It has excellent thermal stability, thermomechanical properties, high glass transition temperature, low water absorption and excellent flame retardancy. These properties make phthalonitrile resins have broad application prospects in fields such as composite materials, aerospace, marine ships, and electronic packaging.

[0003] Studies have shown that pure phthalonitrile monomer is difficult to cross-link and solidify to form phthalonitrile resin due to its molecular structure rigidity and low reactivity and other factors, which greatly Limit the processing and application of phthalonitrile resin. Researchers have found that active hydrogen...
