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 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.
