Compositions and methods for inhibiting polymerization of ethylenically unsaturated monomers.

摘要

A compsn for inhibiting the polymerisation. of ethylenically unsatd. monomers comprises (a) a methoxy cpd. selected from eugenol and 2-tert.-butyl-4-hydroxyanisole, and (b) a phenylenediamine cpd. Also claimed is a method for inhibiting the polymerisation. of ethylenically unsatd. monomers comprising adding to the monomers an effective amt. of the inhibiting compsn.
