HYPERBRANCHED BORIC ACID MODIFIED PHTHALONITRILE MONOMER, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF

WIPO Patent Application WO/2023/083035

A1

The present application discloses a hyperbranched boric acid modified phthalonitrile monomer, a preparation method therefor, and an application thereof. The preparation method for the hyperbranched boric acid modified phthalonitrile monomer comprises: reacting a first mixed reaction system that contains a boron source, a phenol compound, and a solvent to prepare a B-O structure-containing compound; and reacting a second mixed reaction system that contains the B-O structure-containing compound, 4-nitrophthalonitrile, a catalyst, and a solvent to prepare the hyperbranched boric acid modified phthalonitrile monomer. The hyperbranched boric acid modified phthalonitrile monomer prepared in the present application can be dissolved in various organic solvents, and the processing properties of the phthalonitrile monomer are improved; moreover, a modified phthalonitrile resin prepared from the phthalonitrile monomer has excellent high-temperature resistance and ablation resistance properties, and has a wide application prospect in the fields of aerospace, warship submarines, electronic packaging and the like.
