| titleOfInvention | Method for preparing phthalonitrile resin condensate by using amino-terminated polyarylether curing agent containing phthalazinone biphenyl structure |
| abstract | The invention provides a method for preparing a phthalonitrile resin cured product by using an amino-terminated polyarylether curing agent containing a phthalazinone biphenyl structure, belonging to the technical field of material science. The polyarylether containing phthalazinone biphenyl structure and amino-terminated polyarylether is used as a curing agent to be mixed with a phthalonitrile resin precursor, and the mixture is cured by temperature programming. The amino-terminated polyarylether curing agent containing phthalazinone biphenyl structure has excellent thermal stability, and a cured resorcinol-based phthalonitrile resin prepared by using the curing agent has a thermal weight loss temperature of 5% which can reach 553.2 ℃ at most, a carbon residue rate of 78.1% at most at 800 ℃ and a glass transition temperature of above 400 ℃ in a nitrogen atmosphere; the melt viscosity is 0.167 Pa.s at the lowest, and the excellent melt processing fluidity is shown; has a wide processing window, and can reach 194.6 ℃ at the maximum. The cured phthalonitrile resin has excellent thermal stability and thermomechanical property. |
