ABSTRACT:
A conductive silicone rubber composition is prepared by mixing an organopolysiloxane having an aminoalkyl radical, an organopolysiloxane having a (meth)acryloxyalkyl or glycidoxyalkyl radical, and conductive carbon black to form silicone rubber composition (A) in which the carbon black is fixed, and then mixing it with a silicone rubber composition (B) comprising a dimethylpolysiloxane. The composition has stable resistivity in the semiconductive region independent of molding conditions.
