ABSTRACT:
Disclosed is a process for inhibiting polymerization of polymerizable ethylenically unsaturated monomers such as hydrocarbons, acids and esters, wherein manganese nitrite, i.e. Mn(NO.sub.2).sub.2, is employed as an inhibitor. A composition including a polymerizable ethylenically unsaturated monomer and Mn(NO.sub.2).sub.2 is also disclosed. In two preferred embodiments, acrylic acid and styrene, respectively, are the monomers.
