    摘要: Quaternary ammonium compounds of the formula ##STR1## where R.sup.1 and R.sup.2 are identical or different and each is H, halogen, phenyl, alkyl, alkoxy or alkylthio,R.sup.3 is H or alkyl, hydroxyalkyl, cycloalkyl or aralkyl,R.sup.4 and R.sup.5 are identical or different and each is alkyl, phenyl, cycloalkyl or aralkyl orR.sup.4 and R.sup.5 together are a --(CH.sub.2).sub.4 -- bridge, a --(CH.sub.2).sub.5 -- bridge or a --(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 -- bridge,R.sup.6 is alkyl andX.sup..crclbar. is Cl.sup..crclbar., Br.sup..crclbar., I.sup..crclbar., CH.sub.3 SO.sub.4.sup..crclbar. or C.sub.2 H.sub.5 SO.sub.4.sup..crclbar., a process for their preparation from Mannich bases of the formula ##STR2## 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.
