WIPO Patent Application WO/2022/004596
Kind Code:
A1
Abstract:
[Problem] To provide: a mixture which contains a benzoxazine compound and has compatibility with other resins (preferably with epoxy compounds), and which enables a curable composition that contains this mixture to form a cured product having high heat resistance; and a curable composition which contains this mixture. [Solution] The present invention uses a mixture of a compound that is obtained by condensing a p-amino phenol, an aromatic primary monoamine, a bisphenol and a formaldehyde, said mixture containing a benzoxazine compound represented by formula (1), while having a number average molecular weight of from 600 to 1,500. This mixture contains a benzoxazine compound represented by formula (1) wherein the sum of m and n is 1 or more; and the proportion of a benzoxazine compound represented by formula (1) wherein m and n are 0 is 20% by area or less relative to the total amount of the mixture. The present invention also uses a curable composition which contains this mixture.
