Title
(EN) BENZOXAZINE COMPOUND-CONTAINING MIXTURE, CURABLE COMPOSITION CONTAINING THE SAME, AND CURED PRODUCT OBTAINED BY CURING THE CURABLE COMPOSITION
(JA) ベンゾオキサジン化合物含有混合物、これを含む硬化性組成物および該硬化性組成物を硬化させてなる硬化物
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide 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, and to provide a curable composition thereof.

SOLUTION: Used are a mixture, which is a mixture of compound obtained by condensing a p-aminophenol, an aromatic primary monoamine, a bisphenol, and a formaldehyde, and the mixture contains a benzoxazine compound represented by the following formula (1), the number average molecular weight of the mixture is 600 to 1500, a benzoxazine compound in which the total value of m and n in the following formula (1) is 1 or more is contained, and the ratio of the benzoxazine compound in which m and n in the following formula (1) are 0 to the total amount of the mixture is 20 area% or less, and a curable composition that contains the same.
