Abstract
Cured silicone rubber in the form of a finely divided powder is prepared by (1) dispersing a heat-curable liquid silicone rubber composition in water maintained at a temperature of from 0.degree. to 25.degree. C., (2) dispersing the resultant dispersion in a liquid heated to a temperature of at least 50.degree. C., and (3) recovering the resultant cured powder. The liquid silicone rubber composition is preferably maintained at a temperature of from -60.degree. to 0.degree. C. before being emulsified and said liquid is preferably water.
