BENZOXAZINE COMPOUND, METHOD FOR PRODUCING SAME, AND BENZOXAZINE RESIN

WIPO Patent Application WO/2017/164260

A1

The present invention provides a novel benzoxazine compound represented by formula (1), from which a highly heat-resistant cured product can be obtained. The present invention also provides a method for producing a benzoxazine compound, the method including a benzoxazine ring-forming reaction of simultaneously reacting [A] a nitrogen-containing phenol derivative 1, a diamine and formaldehyde or a derivative thereof or a benzoxazine ring-forming reaction having a step 1 of reacting [B] a nitrogen-containing phenol derivative 2 with a diamine so as to obtain an intermediate 1, a step 2 of chemically reducing the intermediate 1 and further reacting with a phenol derivative so as to obtain an intermediate 2, and chemically reducing the intermediate 2 and then reacting with formaldehyde or a derivative thereof. [In formula (1), X is a divalent organic group.]
