ABSTRACT:
A method of polymerizing a thermosetting resin such as an epoxy resin charged with silver particles in which shaped bodies of the resin are brought cold into contact with vapor of an organic liquid boiling at a temperature of above 100.degree. C. so that a condensate from this liquid forms on the bodies in temperature equilibrium so that the heat of vaporization is transferred upon such condensation rapidly to the bodies and the latter are polymerized rapidly under the constant temperature and pressure conditions.
