1. A modified polyhedral polysiloxane, comprising a constitutional unit represented by the formula:
[WR32SiOSiO3/2]a[XR52SiOSiO3/2]b[R43SiOSiO3/2]c wherein a+b+c is an integer of 6 to 24, a is an integer of 1 or more, and b and c are each 0 or an integer of 1 or more; R3 and R5 are each an alkyl group or an aryl group; R4 is a substituent group other than an alkenyl group and a hydrogen atom; W is a group having a structure represented by the following formula (3) or (4), wherein in the case where there are a plurality of Ws, the structures of the formula (3) or (4) may be different from each other, or the structures of the formulas (3) and (4) may coexist; and X is a group having a structure represented by the following formula (5) or (6), wherein in the case where there are a plurality of Xs, the structures of the formula (5) or (6) may be different from each other, or the structures of the formulas (5) and (6) may coexist, wherein l is an integer of 2 or more; m is an integer of 0 or more; n is an integer of 2 or more; R is an alkyl group or an aryl group; Y1 is an epoxy group-containing group, a hydrogen atom, an alkenyl group, an alkyl group, or an aryl group, and the Y1s may be the same as or different from each other; and Z1 is an epoxy group-containing group, a hydrogen atom, an alkenyl group, an alkyl group, or an aryl group, and the Z1s may be the same as or different from each other, provided that at least one of the Y1s and Z1s is an epoxy group-containing group, wherein l is an integer of 2 or more; m is an integer of 0 or more; n is an integer of 2 or more; R is an alkyl group or an aryl group; Y2 is a hydrogen atom, an alkenyl group, an alkyl group, or an aryl group, and the Y2s may be the same as or different from each other; and Z2 is a hydrogen atom, an alkenyl group, an alkyl group, or an aryl group, and the Z2s may be the same as or different from each other, provided that at least one of the Y2s and Z2s is a hydrogen atom. |
