Abstract: Quaternary ammonium compounds of the formula where R1 and R2 are identical or different and each is H, halogen, phenyl, alkyl, alkoxy or alkylthio, R3 is H or alkyl, hydroxyalkyl, cycloalkyl or aralkyl, R4 and R5 are identical or different and each is alkyl, phenyl, cycloalkyl or aralkyl or R4 and R5 together are a -(CH2)4- bridge, a -(CH2)5- bridge or a -(CH2)2-O-(CH2)2- bridge, R6 is alkyl and X(-) is Cl(-), Br(-), I(-), CH3SO4(-) or C2H5SO4(-), a process for their preparation from Mannich bases of the formula and alkylating agents, and the use of these quaternary ammonium compounds as initiators for the photopolymerization of polymerizable mixtures containing olefinically unsaturated compounds, especially for the preparation of aqueous polymer dispersions or polymer solutions.
