Solid solutions of polymeric phenols and polyamines as epoxy curing
agents
摘要:
Curable liquid compositions comprise(A) a liquid epoxide resin and(B) as curing agent for (A), more than 10% by weight, based on the weight of (A), of a solid solution of a polymeric phenol, such as a polymer of p-vinyl phenol or a phenolic novolak resin, and a polyamine having at least one primary amine group, such as diethylenetriamine or triethylenetetramine, the solid solution (B) being disposed as a powder in the epoxide resin. The compositions are useful as adhesives.
