Abstract

The invention relates to the use of triazenes of formula (I) wherein Q is a direct bond or a bivalent radical —(CR8R9)—, Z1 is —O—, —NR10—, —CH2—, —(CR11R12)— or —C(═O)— and R1 to R12 are optionally substituted hydrocarbon residues, as precursors for radicals useful in reactions triggered by free radicals, such as polymerization of unsaturated monomers and degradation of polyolefins. Most of the triazenes of formula (I) are novel and claimed, too, as well as the preparation of triazenes of formula (I) and polymerizable compositions comprising them.
