Abstract:
1. A UV-absorbing polymer comprising the polymerization reaction product of: a first ethylenically unsaturated monomer comprising a first pendant group that comprises a UV-absorbing moiety, and a second pendant group selected from the group consisting of H, or C a second ethylenically unsaturated monomer selected from the group consisting of monomethacryloxypropyl polydimethylsiloxane and methacryloxypropyl trimethoxysilane, wherein the number of repeat units of said first reacted monomer per molecule is from about 1 to about 6000 and the number of repeating units of said second reacted monomer per molecule is from about 2 to about 6300, said UV-absorbing polymer having a weight average molecular weight of at least 2000 and comprising at least 5 mole % of said first pendant group.
