Dental materials based on redox systems with oligomeric cumene hydroperoxide derivatives

Cumene hydroperoxide oligomer according to Formula (I):in which OLIGOMER is a homo- or copolymer chain, which is substituted n times by the group which is in brackets; Q is absent or is a divalent aromatic C6-C14 hydrocarbon radical or an aliphatic, linear or branched C1-C14 hydrocarbon radical, which can be interrupted by one or more S and/or O atoms and/or -O-CO-NR1- and which can be substituted by one or more substituents; X, Y independently of each other in each case are absent, -O-, -COO-; -CONR3- or -O-CO-NR4-, wherein X is absent if Q is absent, and wherein the substitution on the aromatic compound is effected in position 2, 3 or 4 relative to the cumene hydroperoxide group; and n is a value from 1 to 50.
