| 摘要 |
<p>The present invention provides an organopolysiloxane composition comprising (A) a mixture of (A-1) an organopolysiloxane which has unsaturated aliphatic groups each bonded to a silicon atom at each of the both terminals and at least one silmethylene bond in the molecule, (A-2) an organopolysiloxane which has an unsaturated aliphatic group bonded to a silicon atom at only one terminal and at least one silmethylene bond in the molecule, and (A-3) an organopolysiloxane which has at least one silmethylene bond in the molecule and no unsaturated aliphatic group bonded to a silicon atom at any of the terminals; (B) an organohydrogenpolysiloxane which has at least three hydrogen atoms each bonded to a silicon atom in the molecule and (C) a catalytic amount of a hydrosilylation catalyst, and a cured product obtained by curing the composition.</p> |
