A reactive diluent of the formula: [CH2 = CH(CH3)2SiO]2Si(C6H5)2 is added to an organopolysiloxane composition in which the organopolysiloxane has at least 8 Si atoms and 67 to 85 mol % C6H5SiO3/2 and 33 to 15 mol % CH2 = CH(CH3)2SiO1/2 units, containing both platinum catalyst and a silicon hydride crosslinker, so as to give good handling properties combined with valuable mechanical properties. |
