Title:
オキサジン樹脂組成物及びその硬化物
Document Type and Number:
Japanese Patent JP6799376
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide an oxazine resin composition which is excellent in heat resistance and has good dimensional stability even at industrial curing conditions of low temperature and short time, and a cured product the oxazine resin composition. The oxazine resin composition comprises an oxazine resin (A) and an epoxy resin (B), wherein the oxazine resin (A) is represented by the following formula (1). In gel permeation chromatography (GPC) measurement, the oxazine resin composition has 15% or less of a content for the body of n = 35% to 70% of a total content for bodies of n = 1 and n = 2, 50% or less of a content for the body of n = 3 or higher, and a molecular weight distribution with a number average molecular weight of 400 to 2500. In chemical formula 1, A_1 is an aromatic ring group selected from a benzene ring, a naphthalene ring, and a biphenyl ring; X is a divalent cross-linking group; m is 1 or 2; and n is 1 to 5.
