Abstract

PURPOSE: To obtain a curing agent for epoxy resin, having low contents of remaining phenol and amine and low viscosity, by reacting a phenol with an amine and an aldehyde, followed by adding acrylonitrile to the prepared compound.
CONSTITUTION: 1mol phenol (e.g., ortho-cresol, etc.) is mixed with 2W2.5mol amine (e.g., meta-xylenediamine, etc.), and reacted with 1.2W2.0mol aldehyde (e. g., formaldehyde, etc.) at 70W100°C with stirring. The prepared compound is heated at 100W180°C so that the formed water is eliminated, and 0.2W1.5mol acrylonitrile is added to it, to give the desired reaction product.
EFFECT: The content of the remaining phenol is ≤5wt%, and that of the amine is ≤35wt%, and the viscosity is ≤8,000cps (25°C).
