    摘要: An optically clear platinum-group metal curable liquid silicone rubber composition having good physical properties. The composition comprises a vinyldimethylsiloxy-terminated polydimethyl(diphenyl)siloxane copolymer comprising about 1 to 20 mole percent diphenylsiloxy units and having a viscosity within a range of about 20,000 mPa.multidot.s to 100,000 mPa.multidot.s at 25.degree. C., vinyldimethylsiloxy-terminated polydimethyl(diphenyl)siloxane copolymer comprising about 1 to 20 mole percent diphenylsiloxy units and having a viscosity within a range of about 50 mPa.multidot.s to 10,000 mPa.multidot.s at 25.degree. C. and optionally comprising up to about 3 mole percent vinyldimethylsiloxy units, a treated reinforcing silica filler, and curing agents.
