PURPOSE:The titled molded article having improved transparency, heat resis tance, dimensional stability, etc., obtained by blending a liquid epoxy resin with a specific quaternary phosphonium salt as a curing agent to give a composi tion and curing it into a desired shape. CONSTITUTION:A liquid epoxy resin is blended with 0.5wt% quaternary phosphonium salt (e.g., tetra-n-butylphosphonium bromide, etc.,) shown by the formula (X is halogen; R1-R4 are H, 1-8C alkyl, phenyl or aryl) as a curing agent. The prepared epoxy resin composition is cured into a desired shape, to give the aimed molded article. |
