Abstract

Organopolysiloxane modified organic polymers are prepared by reacting organic polymers containing C-bonded hydroxyl groups with organopolysiloxanes containing Si-bonded hydroxyl groups and/or alkyl groups which are bonded to silicon via oxygen in the presence of water in excess of any formed during the reaction.
