A process for the manufacture of polyorganosiloxanes having ionic groups and reactive functional groups includes (a) conversion of a low molecular weight aralkylene modified polysiloxane to a corresponding sulfonic acid functional material by treating the low molecular weight aralkylene modified polysiloxane with a sulfonating agent; (b) subjecting the reaction product obtained in step (a) to an equilibration reaction with an acid catalyzed ring opening polymerization-effective polyorganosiloxane; and (c) subjecting the reaction product obtained in step (b) to a hydrosilylation reaction with an unsaturated hydrocarbon containing at least one epoxy group, an unsaturated hydrocarbon containing at least two unsaturation moieties, an unsaturated hydrocarbon containing at least one sulfur heteroatom, an unsaturated hydrocarbon containing a monovalent organosilane group, an unsaturated hydrocarbon containing one hydroxyl containing group, an unsaturated hydrocarbon containing one or more of a halogen, carboxylate, imine, isocyanate, amide, nitrile or tertiary amine with other than alkyl groups moiety.
