Abstract

Silicone rubber compositions, of the addition curable type, comprise as a base polymer a vinyl-containing organopolysiloxane having a tetraorganosilethylenesiloxane unit of the following general formula: ##STR1## wherein R.sup.1 to R.sup.4 are each a monovalent hydrocarbon group of from 1 to 10 carbon atoms. The silicone rubber composition gives a cured product having high strength, for example, a tensile strength of 30 kg/cm.sup.2 or above, without compounding fillers or reinforcing agents.
