Preparation of polyether ester liquid crystal epoxy resin: Liquid crystal epoxy resin and p-phenylenediamine undergo thermal curing reaction, and network materials with liquid crystal texture can be obtained under different curing conditions.
Synthesis of polyether epoxy resin: The synthesis of polyether epoxy resin liquid crystal directly uses epichlorohydrin to generate liquid crystal epoxy resin under the action of strong alkali. This type of epoxy resin has a higher molecular weight. Liquid crystal polyether epoxy resin, liquid crystal epoxy resin produces liquid crystal phase transition at 115-152 ℃, and it has better electrical and thermal properties with the cured product of trimellitic acid monoanhydride and diphenyl sulfone diamine.
