P.A.T H-Tempo (also referred to as 4-Hydroxy-TEMPO) is used as a stabilizer for countering oxidation and/or the polymerization of unsaturated compounds such as acrylic acid, butadiene, styrene, etc. H-TEMPO is also used as a shortstopper for radical polymerization processes, e. g. in the manufacture of oligoester acrylates.
