Abstract

The invention discloses an animophenoxy phthalonitrile resin monomer and a synthetic method thereof. The molecular structural formula of the animophenoxy phthalonitrile resin monomer is shown as formula (I). The synthetic method comprises the following steps: (1) 2-aminophenol, a catalyst and a solvent are mixed, and the mixture is heated to 90-100 DEG C under nitrogen protection and subjected to heat preservation; (2) 3-nitrophthalonitrile is added to the solution subjected to heat preservation, the materials react at the temperature of 80-90 DEG C, and the animophenoxy phthalonitrile resin monomer is obtained. The animophenoxy phthalonitrile resin monomer has the advantages of high reaction activity, high heat resistance, low curing temperature and short curing time, and the synthetic method is simple, convenient and low in cost.

Description

technical field [0001] The invention belongs to the technical field of organic synthetic polymer materials, and relates to a self-catalyzed nitrile-based resin monomer and a synthesis method thereof, in particular to an aminophenoxyphthalonitrile resin monomer and a synthesis method thereof. Background technique [0002] Aerospace, national defense and military fields have put forward new requirements for composite materials with high temperature resistance, high performance and good flame retardancy. Phthalonitrile resins are favored for their cured products with good thermal stability and mechanical properties, as well as excellent thermo-oxidative stability, flame retardancy and good moisture resistance. At present, this kind of resin has been widely used in the fields of aerospace, shipbuilding, microelectronics and machinery manufacturing. [0003] At present, typical phthalonitrile resins mainly include biphenyl type bisphthalonitrile resin, bisphenol A type bisphthal...
