Abstract: The invention encompasses a composition of vinyl compounds, comprisinga) at least one polymerizable compound which has at least one O-vinyl group or one N-vinyl group, andb) at least one ammonium salt of the formula (I)where R is NH2, O NH4 , C1-C18-alkyl, C6-C18-cycloalkyl, or C7-C18-alkylcycloalkyl.The invention further relates to the use of an ammonium salt of the formula (I) as additive to polymerizable compounds which have at least one O-vinyl group or one N-vinyl group, and also to a process for inhibiting premature polymerization of compositions which comprise polymerizable compounds which have at least one O-vinyl group or one N-vinyl group, which encompasses adding to the compositions an ammonium salt of the formula (I).
