SUBSTANCE MIXTURES COMPRISING VINYL-CONTAINING COMPOUNDS ANDSTABILIZERS

摘要

The invention concerns substance mixtures containing: (A) compounds containi ng vinyl groups; (B) an active amount of a mixture which inhibits premature polymerization of the compounds containing vinyl groups and contains: (i) at least one N-oxyl compound of a secondary amine which does not carry any hydrogen atoms on the .alpha.-carbo n atoms; and (ii) at least one iron compound; (C) optionally nitro compounds; and (D) optionally co-stabilizers. The invention further concerns a process for inhibiting the premature polymerization of compounds (A) containing vinyl groups, and the use of mixture (B), optionall y mixed with nitro compounds (C) and/or co-stabilizers (D), for inhibiting the premature polymerization of radically polymerizable compounds and for stabilizing organic materials against the harmful effect of radicals.
