Abstract
The viscosities of solventless compositions of epoxy resins containing 1,2 epoxy groups and having at least two epoxide groups per molecule and effective amounts of hardener are markedly reduced whereby they are useful for vacuum-pressure impregnation, pre-impregnation electrical insulating material and structural composite applications by addition of a reactive diluent comprising an aromatic vinyl monomer.
