    • Organopolysiloxanes having quaternary ammonium groups are prepared by first,condensing organopolysiloxanes having a terminal unit HO—SiR22O1/2  (I) with aminosilanes AaRbSi(OR1)4-(a+b)  (II), where A is a monovalent SiC-bonded organic radical containing at least one tertiary amino group and free of primary or secondary amino groups, R a monovalent C1-18 hydrocarbon radical, R1 is a C1-8 alkyl radical, a is 1 or 2, b is 0 or 1, and a+b is 1 or 2, optionally with catalysts, to obtain organopolysiloxanes having tertiary amino groups, and, second, partly or fully quaternizing the organopolysiloxanes obtained in the first step with alkylating agents, no bases being added in the second step, and water is substantially absent.
