Abstract:
1. A silicon-containing curable composition comprising: a prepolymer (A) containing two or more Si—H groups in one molecule, which is obtainable by subjecting one or more cyclic siloxane compounds (α) represented by formula (1) and one or more compounds (β) represented by formula (2), to a hydrosilylation reaction; a cyclic siloxane compound (B) containing, in one molecule, two or more carbon-carbon double bonds that are reactive with Si—H groups; a polysiloxane compound (C) represented by formula (7), formula (8), formula (9), formula (10) or combinations thereof; and a hydrosilylation catalyst (D), wherein R R the symbol a represents a number from 2 to 10; and the symbol b represents a number from 0 to 8, and a +b ≧2; wherein n is 1 or 2; wherein R x, y, z and r each independently represents a number from 0 to 10, and 1≦x+y+z+r≦10; wherein R R at least one of R s, t, u and w each independently represents a number from 0 to 10, and 1≦s+t+U+W≦10; wherein R c, d, e and f each independently represents a number from 0 to 10, and 1≦c+d+e+f≦10; wherein R R at least one of R g, h, i and j each independently represents a number from 0 to 10, and I≦g+h+i+j≦10.
