ABSTRACT:
A process for preparing aqueous emulsions from high-molecular-weight organopolysiloxanes which are solid at room temperature, in the absence of organic solvents, which comprises dissolving the high-molecular-weight organopolysiloxane which is solid at room temperature in a low-molecular-weight organo(poly)siloxane which is liquid at room temperature, and emulsifying this solution with water in the presence of an emulsifier and other additives, if desired.
