<P>PROBLEM TO BE SOLVED: To provide an organopolysiloxane composition and a cured product, excellent in molding workability, transparency, heat resistance, light resistance, and gas barrier properties. <P>SOLUTION: The organopolysiloxane composition comprises: (A) a hydrosilyl group-containing polyhedral structure polysiloxane modified product obtained by hydrosilylation reaction of a polysiloxane compound (b) obtained by hydrosilylation of polyhedral structure polysiloxane compounds (a) containing an alkenyl group and a hydrosilyl group with each other, with a compound (c) containing a hydrosilyl group or an alkenyl group; and (B) a compound containing two or more alkenyl groups, wherein the (B) component is at least one selected from aromatic compounds containing two or more alkenyl groups, alicyclic hydrocarbon compounds containing two or more alkenyl groups, divinylsilane compounds, and the like. <P>COPYRIGHT: (C)2012,JPO&INPIT |
