Claim 0:
1. A composition comprising at least one (meth)acrylic monomer, at least one vinyl containing monomer and at least one polymerizable hydrophilic side-chain siloxy-based methacrylate monomer of having the formula:, wherein:
R1 is hydrogen or methyl;
Y1 and Y2 are independent of one other and each comprise a linkage selected from the group consisting of a direct bond, O, NRa, C(O), C(O)NRa, NRaC(O), OC(O)NH, NHC(O)O, NRaC(O)NH, NHC(O)NRa, C(O)O, OC(O), NHC(O)NHZ0—NH—C(O)NH, OC(O)NHZ0—NH—C(O)O, OC(O)NHZ0—NH—C(O)NH, and NHC(O)NHZ0—NH—C(O)O; where Ra is H, C1-C4 alkyl or C1-C3 alkanol, and Z0 is a linear or branched C2-C12 alkylene divalent radical, or a C5-C7 cycloaliphatic divalent radical, each of which include one or more linkages of O, NRa and C(O);
Z1 and Z2 are independent of one other and each are selected from the group consisting of a direct bond, a C1-C12 unsubstituted or substituted, and a linear or branched alkylene divalent radical, where each alkylene divalent radical includes one or more linkages of O, NRa, and C(O), an unsubstituted phenylene divalent radical, a C5-C7 cycloaliphatic divalent radical, and a C7-C12 arylalkyne divalent radical, wherein at least two of the groups Y1, Y2, Z1 and Z2 is not a direct bond,
R2 are the same or different and are selected from low alkyl or phenyl groups and alkyl siloxy groups including: —O—Si (CH3)2—X where X is selected from lower alkyl, phenyl, or hydrophilic functionalities,
R3 is selected from low alkyl, phenyl groups and alkyl silyl groups including: —Si(CH3)2—X where X is selected from lower alkyl, phenyl, and hydrophilic functionalities,, wherein in at least one of R2 or R3, X is selected from the group consisting of, , Where R4 is independent of one other and is a linkage selected from the group consisting of a direct bond, O, NRa, C(O), C(O)NRa, NRaC(O), OC(O)NH, NHC(O)O, NRaC(O)NH, NHC(O)NRa, C(O)O, OC(O), NHC(O)NHZ0—NH—C(O)NH, OC(O)NHZ0—NH—C(O)O, OC(O)NHZ0—NH—C(O)NH, and NHC(O)NHZ0—NH—C(O)O; where Ra is H, C1-C4 alkyl or C1-C3 alkanol, and Z0 is a linear or branched C2-C12 alkylene divalent radical, R5 is CH3, and
n is an integer from 1-3.
