Claim:
1. A composition prepared by a bulk polymerization method comprising forming a mixture consisting essentially of a first multifunctional monomer comprising alkenyl groups and a second multifunctional monomer comprising moieties that are reactive with alkenyl groups, reacting said first multifunctional monomer with said second multifunctional monomer to form a partially cross-linked prepolymer gel and thereafter curing the prepolymer to form a bulk polymer having the general structure (I): wherein: M is an organic moiety which has any of the following ring structures wherein each N 1 , N 2 , and N 3 is independently selected from the group consisting of N, O, S, Se, Sb, P, Ge, Sn, Te, Ga, In, Ni, Co, Ti, Zr, and W, and each methylene group is unsubstituted or substituted with a hydrocarbyl having 1 to 3 carbon atoms, O, N or S; X is a main group element selected from the group consisting of S, P, Se and combinations thereof; R R R Y has a value of 0, 1, 2, 3, or 4; Z has a value of 0, 1, 2, 3, or 4; YY has a value of 0, 1 or 2; and Y, YY, and Z are such that the total number of moieties bonded to M is 3, 4, 5, or 6; and n represents the number of repeat units in the polymer, and wherein at least 90% of functional groups in the bulk polymer are reacted.
