What are the approximate mechanisms of action of the antioxidants and polymerization inhibitors used in benzene hydrogenation?

Preservative: Monoethanolamine; Antipolymerization agent: Unknown (prevents the polymerization of dienes and styrene). I’d like to know about their mechanism of action?
Preservatives all work on the same principle: forming a protective film on the metal surface. The same principle applies to inhibitors as well: they form a film on the surface of the molecules. For example, water in oil, oil in water.
