Abstract
Abstract Quaternary ammonium salts of chloromethylated silanes or siloxanes which contain at least one [Cl.sup.-R.sub.3 "N.sup.+CH.sub.2 --Ar--(R).sub.n ] radical directly linked to a silicon atom wherein Ar is an arylene radical, wherein R 3 "N taken collectively is a tertiary amine radical and wherein the compounds are useful in conventional silicon applications such as anti-static agents, wetting agents, lubricants, hydraulic fluids, coating resins, elastomers and cationic surfactants.
