Abstract
A stabilized composition consists essentially of unsaturated hydrocarbon-based materials, and a stabilizer selected from the group consisting of a hydroxybenzophenone and a nitroxyl radical based stabilizer.A stabilized composition consists essentially of unsaturated hydrocarbon-based materials, at least one polar liquid and a stabilizer selected from the group consisting of a hydroxybenzophenone, a nitroxyl radical based stabilizer and a hydroquinone based stabilizer.A method for stabilizing unsaturated hydrocarbon-based precursor material against the polymerization comprises providing a stabilizer selected from the group consisting of a hydroxybenzophenone and a nitroxyl radical based stabilizer.A method for stabilizing a mixture of unsaturated hydrocarbon-based precursor material with at lease one polar liquid against the polymerization comprises adding to the mixture, a stabilizer selected from the group consisting of a hydroxybenzophenone and a nitroxyl radical based stabilizer.
