    摘要： Radically polymerizable dental material, which includes a combination of a hydroperoxide and a thiourea derivative according to the following Formula (I) as initiator system for the radical polymerization: in which R is absent or is an (n+1)-valent, aromatic, aliphatic, linear or branched C1-C50 hydrocarbon radical, which can be interrupted by one or more ether, thioether, ester, amide or urethane groups; PG is a radically polymerizable (meth)acrylate, (meth)acrylamide or vinyl group; and n is 1, 2 or 3.

    摘要： Compounds according to general formula (I) in which M is Ge or Sn, RAr is R1, R2, R3, R4, R5, independently of one another in each case, are —H, —F, —Cl, —OR6, —SR6, —N(R6)2, —CF3, —CN, —NO2, —COOR6, —CONHR6, a branched, cyclic or preferably linear C1-20 alkyl, C2-20 alkenyl, C1-20 alkyloxy or a C2-20 alkenoxy radical, which can be interrupted one or more times by O, S or —NR6— and substituted by one or more polymerizable groups and/or radicals R6, R6 is H, a branched, cyclic or preferably linear C1-20 alkyl or C2-20 alkenyl radical, R7 is a chemical bond, an n-valent aromatic radical or a branched, cyclic or preferably linear C1-20 alkylene radical, which can be interrupted one or more times by O, S or —NR6— and substituted by one or more polymerizable groups, ═O and/or radicals R6, n is 2 or 3 and m is 0 or 1. The compounds are particularly suitable as photoinitiators for radical polymerization and in particular for the production of dental materials.
