Polymerizable compositions with acylgermanes as initiatiors

摘要

Composition with at least one polymerizable binder and a polymerization initiator, which contains at least one acylgermane according to general Formula (I), in which R⁰ is a substituted or unsubstituted C_1-18-alkyl radical or an acyl group; R¹ and R² are H, an acyl group or have one of the meanings given for R³; R³ is a branched or linear C_1-18-alkyl radical which can be unsubstituted or substituted one or more times by -O-, -NH-, -NR-, -S- or interrupted by other groups, trimethylsilyl, hal-(CH₃)₂Si-[OSi(CH₃)₂]_r^-, (CH₃)₃Si-[OSi(CH₃)₂]_r-, -COOH, -COO-R¹⁰, -CO-NR¹¹R¹², -CO-vinyl, -CO-phenyl, phenyl-C_1-4-alkyl, phenyl, naphthyl or biphenyl, C_5-12 cycloalkyl, a 5 or 6-membered O, S or N-containing heterocyclic ring, halogen, OH, an aromatic C_6-30 radical which can be substituted or unsubstituted and/or interrupted by O, S or -NR-, or a branched, cyclic or linear C_1-20 alkyl, -alkenyl, -alkoxy or -alkenoxy radical; m is 1, 2 or 3; n is 0 or 1 and p is 0 or 1; and the use of acyl germanes of Formula (I) for example as initiator for radical polymerization.
