Triarylsulfonium salts of formula I or II are useful as initiators for cationic photopolymerizations: (FI + FII) wherein Ar1 and Ar2 are independently polycyclic aryl, substituted aryl, heteroaryl, substituted heteroaryl, or aryl or heteroaryl, pendant from a polymer chain; and MtXn.macr. is a complex anion selected from PF6.macr., SbF6.macr., AsF6-, GaF6.macr., BF4.macr., (C6F5)4B.macr. and CF3SO3.macr., C9F19SO3.macr. and (CF3SO2)3C.macr..
L'invention concerne des sels de triarylsulfonium de formule (I) ou (II) que l'on utilise comme initiateurs pour des photopolymérisations cationiques, dans lesquelles Ar?1¿ et Ar?2¿ désignent indépendamment aryle polycyclique, aryle substitué, hétéroaryle, hétéroaryle substitué ou aryle ou hétéroaryle, pendant à partir d'une chaîne polymère; et MtX¿n??.macr.¿ désigne un anion complexe sélectionné dans PF¿6??.macr.¿, SbF¿6??.macr.¿, AsF6-, GaF¿6??.macr.¿, BF¿4??.macr.¿, (C¿6?F¿5?)¿4?B?.macr.¿ et CF¿3?SO¿3??.macr.¿, C¿9?F¿19?SO¿3??.macr.¿ et (CF¿3?SO¿2?)¿3?C?.macr.¿.
