The present invention is directed to a network composition having the reaction product of: (i) at least one anionic polymerizable ethylenically unsaturated monomer (I) selected from the group consisting of [CH2=C(R3)C(O)OXa(C2H4O)b(C3H6O)c(C4H8O)d]pP(O)(OY)q(OZ)r where R3=H or alkyl of 1 to about 6 carbon atoms; X=alkyl, aryl, or alkaryl diradical connecting group of 0 to about 9 carbon atoms; a is 0 to about 100; b is 0 to about 100; c is 0 to about 100; d is 0 to about 100; q is 0 to about 2; r is 0 to about 2; p is 1 to about 3 subject to the limitation that p+q+r=3; and Y and Z is H, or metal ion; and CH2=C(R3)C(O)OXa'(C2H4O)b'(C3H6O)c'(C4H8O)d'-SO3-Y) where R3=H or alkyl of from 1 to about 6 carbon atoms; X=alkyl, aryl, or alkaryl diradical connecting group of 0 to about 9 carbon atoms; a' is 0 to about 100; b' is 0 to about 100; c' is 0 to about 100; d' is 0 to about 100; Y is H, or metal ion; and (ii) one or more additional monomers (II) selected from the group consisting of acrylic acid/acrylate, methacrylic acid/methacrylate, acrylamides, vinyl acetate and styrene, which are copolymerizable with (I); and (iii) a cross-linking agent (III), capable of copolymerizing with (I) and (II). |
