Stabilizers for the Stabilization of Unsaturated Hydrocarbon-Based Precursor

A method for stabilizing an unsaturated hydrocarbon-based precursor material against its polymerization comprising steps of:

• providing the unsaturated hydrocarbon-based precursor material;
• and
• adding to the unsaturated hydrocarbon-based precursor material at least one nitroxyl radical based stabilizer;
• wherein the unsaturated hydrocarbon-based precursor material is selected from the group consisting of 2,5-Norbornadiene (NBDE), Norbornene, and mixtures;
• and
• the at least one nitroxyl radical based stabilizer has a structure of:
• wherein:
• raised period “▪” denotes one unpaired electron;
• R1 through R4 are independently selected from a straight chained or branched, substituted or unsubstituted, alkyl or alkenyl group;
• wherein the substituted group comprises oxygen-containing groups selected from the group consisting of hydroxyl, carbonyl, alkoxide, and carboxylic group;
• and
• R5 and R6 are independently selected from a straight chained or branched, a substituted or unsubstituted, alkyl group or alkenyl group.
