Abstract:
1. A composition formed by reacting compounds comprising: a. a metal-containing precursor unit MU comprising at least one member selected from the group consisting of b. a prepolymer unit PU containing at least two ethylenically unsaturated functional groups and at least one oxygen, sulfur or nitrogen atom, c. a catalyst or an initiator capable of inducing a reaction of ethylenically unsaturated functional groups of the metal-containing precursor unit and the prepolymer unit, and d. an inert solvent, wherein 7-90 weight % of compounds containing ethylenically unsaturated functional groups are represented by Structure I, the composition is a homogeneous solution and, after reaction, the composition is optically clear as measured by the Transmittance Test.
