Abstract
In the production of moulded articles from unsaturated monomer-free polyesters with a content of polymerization catalysts, the unsaturated polyesters, optionally in the presence of conventional fillers, are prepolymerized to the gel stage by heating, then cooled and the pre-polymers obtained hardened at any later time by reheating while moulding. Conventional peroxide catalysts may be used or 1,2-substituted ethanes of the general formula
