Abstract

A monomer composition is described, containing A) vinyl-containing monomers in which the vinyl bears a hetero-atom selected from the group consisting of the halogens, nitrogen, oxygen, sulfur or silicon, and PA1 B) at least one N-oxyl compound of a secondary amine which does not bear hydrogen on the .alpha.-carbons, in an amount effective as stabilizer against premature polymerization.
