Abstract
A method of producing a silicone rubber composition, comprising heating a mixture of an organopolysiloxane having a silanol group at both the ends of the molecular chain, a end blocking agent, such as a triorganosilanol, a silane or a siloxane having two dialkylaminosilyl groups in the molecule, and a reinforcing filler thereby carrying out chain lengthening and end blocking of said organopolysiloxane. According to this method, a silicone rubber composition whose low-molecular siloxane content is held down remarkably can be produced without consuming a large amount of energy for the mixing.
