Abstract:
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 a main group element; 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.
