摘要：
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; R3, R4, R9, R10 are each independently of one another C1-C18alkyl, C2-C18alkenyl or C2-C18alkinyl; or R3 and R4 and/or R9 and R10 form together with the linking carbon atom a C3-C12cycloakyl radical; R5, R6, R7, R8 are each independently of one another hydrogen, C1-C18alkyl, C2-C18alkenyl or C2C18alkinyl; X is —O—, —O—C(O)—, —NR2— or —NR2—C(O)—; R2 is hydrogen, C1-C18alkyl or phenyl; if n is 1, R1 is C8-C36alkyl, C8-C36alkenyl or C8-C36alkinyl; if n is 2, R1 is C10-C36alkylen, C10-C36alkenylen or C10-C36alkinylen. 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.
