Process for the preparation of an organopolysiloxane resin

The present invention relates to siloxane copolymers containing alkenyl groups and a process for their preparation. The siloxane copolymers of the present invention can be used in cross-linkable compositions for the production of coatings which repel tacky substances, an example of which would include coatings for release papers or films.

A process for preparing organopolysiloxane hydrosols by mixing an organosilicon compound with water, which comprises mixing a silane of the formula

Process for preparing organopolysiloxane hydrosols

Organosols of organopolysiloxanes are prepared by adding water-soluble organic solvents or mixtures thereof or water-soluble mixtures of water-soluble and water-insoluble organic solvents to aqueous, colloidal suspensions of organopolysiloxanes obtained by adding at least one alkoxysilane and/or the partial hydrolyzate thereof, and, if appropriate, mixed with an organo(poly)siloxane free of alkoxy groups and having a maximum of 8 siloxane units per molecule, to water in the presence of emulsifiers at a maximum rate of 5 moles of organosilicon compound per hour and per liter of water, and subsequently removing the water by distillation.
