Abstract

PURPOSE: An epoxy resin composition having high head and moisture resistance, and improved handleability, prepared by heat-treating an aromatic polyamine and an epoxy resin to increase the viscosity of the mixture without causing gelation.
CONSTITUTION: A composition comprising one or more types of prepolymers obtained by heat-treating an aromatic polyamine (A) of formula I or II: (R1 and R2 are H, methyl, OCH3, -Cl, -Br, or -NH2 groups) with an epoxy resin (B) consisting mainly of an epoxy compound of formula III: (R3, R5, and R6 are H or methyl groups; R4 is H, methyl, or ethyl group) at a weight ratio of (A) to (B) of 0.5W1.2:1 at 50W200°C to increase the viscosity of the mixture to 5 poises or higher at 120°C or above without causing gelation. 4,4'-Diaminodiphenyl sulfone, 3,3'-diamino-dephenyl sulfone, etc. may be cited as the polyamine (A).
