This invention relates to unsaturated polyester resin or vinyl ester resin compositions comprising a polymer containing reactive unsaturations as a resin; a 1,3-dioxo-component, and optionally a reactive diluent and/or an inhibitor and/or a stabilizer; the resin compositions being curable with a peroxide component, and wherein the resin in the resin composition has an acid value=10; and the resin composition contains—while being cured—a base, which is either selected from the group of organic or inorganic oxides, hydroxides, alkoxides or carboxylates for each of which the cation has a redox potential of the metal of at most−1V, or of ammonium ions; or is selected from the group of nitrogen-containing organic compounds. The present invention also relates to objects and structural parts prepared from such resin composition by curing with a peroxide. Finally the invention also relates to methods of peroxide curing of unsaturated polyester or vinyl ester curing and its use in chemical anchoring, roof coatings etc. |
