Polymerizable compositions with acylgermanium compounds

Abstract

Composition with at least one polymerizable binder and at least one polymerization initiator, which contains at least one acylgermanium compound according to general Formula (I), in which Ris a substituted or unsubstituted C-alkyl radical or an acyl group; Rand Rare H, an acyl group or have one of the meanings given for R; Ris a branched or linear C-alkyl radical which can be unsubstituted or substituted one or more times by —O—, —NH—, —NR—, —S— or interrupted by other groups, trimethylsilyl, hal-(CH)Si—[OSi(CH)], (CH)Si—[OSi(CH)]—, —COOH, —COO—R, —CO—NRR, —CO-vinyl, —CO-phenyl, phenyl-C-alkyl, phenyl, naphthyl or biphenyl, Ccycloalkyl, a 5 or 6-membered O, S or N-containing heterocyclic ring, halogen, OH, an aromatic Cradical which can be substituted or unsubstituted and/or interrupted by O, S or —NR—, or a branched, cyclic or linear Calkyl, -alkenyl, -alkoxy or -alkenoxy radical; m is 1, 2 or 3; n is 0 or 1 and p is 0 or 1; wherein in each case two of the radicals R, R, Ror Rcan be connected to each other accompanied by the formulation of a 5 to 8 member ring; and the use of acylegermanium compounds of Formula (I), for example, as initiator for radical polymerization.
