Document Type and Number:
Japanese Patent JP2022013415
Kind Code:
A
Abstract:
To provide a method for producing a benzoxazine compound-containing mixture that has compatibility to other resins (preferably epoxy compound), and, when contained in a curable composition, can impart high heat resistance to the cured product.SOLUTION: Used is a method, which is a method for producing a mixture containing a benzoxazine compound represented by the following formula (1) that includes a step of condensation reacting a p-aminophenol, an aromatic primary monoamine, a bisphenol, and a formaldehyde, and in which the ratio of a phenolic hydroxyl group derived from the p-aminophenol and the bisphenol, and an amino group derived from the p-aminophenol and the aromatic primary monoamine in the condensation reaction step, (OH/NH2), is 1.05/1 to 1.15/1.SELECTED DRAWING: None
