Abstract
Unsaturated polyester resin foams or cellular structures of varying low densities are prepared quickly at ambient temperatures from an admixture which comprises a liquid unsaturated curable polyester resin, an organic isocyanate compound, a suitable surfactant, an accelerator and a particular combination of peroxide curing agents, which also serves to initiate the release of gases that permit expansion of the resin in a controlled manner to obtain a foamed structure.
