<p>Cationically polymerizable materials, such as epoxide resins, phenoplasts, and aminoplasts, are polymerized by passing an electric current through a composition comprising (A) the cationically polymerizable material, and (B) a boron trifluoride complex, between an anode and a cathode in contact with the composition, whereby polymerized material is deposited on the anode. Typical complexes (B) are those of boron trifluoride with primary, secondary, or tertiary amines or with trialkyl or triaryl phosphines. The method is a particularly suitable means for coating conductive substrates, giving a rapid cure without the need for special formulations to render the polymers electrodepositable.</p> |
