Abstract
The present invention relates to a polymerizable composition, comprising a) at least one ethylenically unsaturated monomer or oligomer, b) a radical source capable of starting polymerization of the ethylenically unsaturated monomer or oligomer and c) at least one compound of formula (I), wherein n is 1 or 2; R , R , R , R are each independently of one another C -C alkyl, C -C alkenyl or C -C alkinyl; or R and R and/or R and R form together with the linking carbon atom a C -C cycloakyl radical; R , R , R , R are each independently of one another hydrogen, C -C alkyl, C -C alkenyl or C C alkinyl; X is —O—, —O—C(O)—, —NR — or —NR —C(O)—; R is hydrogen, C -C alkyl or phenyl; if n is 1, R is C -C alkyl, C -C alkenyl or C -C alkinyl; if n is 2, R is C -C alkylen, C -C alkenylen or C -C alkinylen. Further objects of the present invention are a process for polymerization and the use of compounds of formula (I) for the polymerization of ethylenically unsaturated monomers.
