<p>A polymer having a backbone repeat unit that includes at least two metal atoms bonded to each other and only one ethylenically unsaturated functional group wherein the backbone unit preferably has a structure of: -C(R?3)=C(R3)-[C(R3)(R4)]¿n-[M(R1)(R2)]a-[C(R3)(R4)]p-, wherein n is 0 to 4; a is at least 2; p is 0 to 4; R?1 and R2¿ are each independently selected from hydrogen, halogen, lower alkyl having 4 or fewer carbon atoms, alkenyl having 4 or fewer carbon atoms, or aromatic having one ring; R?3 and R4¿ are each independently selected from hydrogen and lower alkyl having 1 to 4 carbon atoms; and M is a metal atom selected from at least one of Sn, Ge, Pb, Hg, Ni, Pd, Pt, Cr, Fe, Co, Cu and Zn. The polymer has at least 20 weight percent metal, preferably at least 50 weight percent metal, based on the weight of the polymer.</p> |
