Abstract
Provided are: a thermally curable composition which contains benzoxazine-based compounds obtained by condensing aromatic diamines, a phenol compound, and an aldehyde compound, the aromatic diamines being a mixture comprising 4,4′-oxydianiline and 3,4′-oxydianiline, the mass ratio of the 4,4′-oxydianiline to the 3,4′-oxydianiline being 50:50 to 80:20; a varnish of the thermally curable composition; and a thermally cured object.
Claims16
A thermosetting composition comprising a benzoxazine compound that is obtained by condensing aromatic diamine, phenols and aldehydes,
- wherein the aromatic diamine is a mixture comprising 4,4′-oxydianiline and 3,4′-oxydianiline, and a mass ratio between the 4,4′-oxydianiline and the 3,4′-oxydianiline is in the range of 50:50 to 80:20.
A thermosetting composition comprising a benzoxazine compound, the composition being obtained by mixing:
- a thermosetting composition (A) containing a benzoxazine compound that is obtained by condensing 4,4′-oxydianiline, phenols and aldehydes;
- and a thermosetting composition (B) containing a benzoxazine compound that is obtained by condensing 3,4′-oxydianiline, phenols and aldehyde,
- wherein a mass ratio between the thermosetting composition (A) and the thermosetting composition (B) is in the range of 50:50 to 80:20.
