Abstract

Organopolysiloxane containing compositions are prepared by mixing an organopolysiloxane containing an aminoalkyl group, an organopolysiloxane containing a fluoroalkyl group, and optionally, organopolysiloxanes containing alkyl groups, together with water, or a water/acid mixture, or a water/acid/alcohol mixture, where the mixture is adjusted to have a pH in the range of 1-8, then removing the alcohol already present or formed during reaction.
