Abstract
Organopolysiloxanes bearing regularly spaced pendent carboxylic acid groups or salts thereof have a block polymer structure and are derived by the double half-esterification of a dianhydride and a silanol- or carbinol-functional organopolysiloxane or sulfur analog thereof. The products can form stable aqueous dispersions without the need for a surfactant.
