1. A silicone monomer comprising of at least one carbosiloxane linkage having the general formulae (I):
(R1R2R3)—Si—Y1—[Si(R4R5)Y2)]a—Si(R6R7)—Z (I)wherein a is 0 to about 100;
Y1 is a substituted or unsubstituted divalent alkyl linking group of 1 to about 10 carbon atoms; Y2 is a substituted or unsubstituted divalent alkyl linking group of 1 to about 10 carbon atoms or a hetero atom; R1, R2, R3, R4, R5, R6, and R7 is independently selected from the group consisting of monovalent aliphatic, cycloaliphatic or aromatic or halogenated hydrocarbon groups of 1 to about 10 carbons, —Y2Si(R8R9R10) and A, wherein R8R9R10 is independently selected from the group consisting of monovalent aliphatic, cycloaliphatic and aromatic hydrocarbon groups of 1 to about 10 carbons; A is a monovalent hydrophilic or hydrophobic moiety selected from the group consisting of substituted or unsubstituted, saturated and unsaturated aliphatic, cycloaliphatic or aromatic hydrocarbons and substituted or unsubstituted, saturated and unsaturated aliphatic, cycloaliphatic or aromatic hydrocarbons containing hetero atoms; Z has the following general formulae (II)
R11—B—X (II)wherein R11 is a linear or branched, divalent alkyl linking group having 0 to about 20 carbon atoms, B is a divalent hydrophilic or hydrophobic moiety selected from the group consisting of substituted or unsubstituted, saturated and unsaturated aliphatic, cycloaliphatic or aromatic hydrocarbons and substituted or unsubstituted, saturated and unsaturated aliphatic, cycloaliphatic or aromatic hydrocarbons containing hetero atoms, wherein B comprises a functionality chosen from an alcohol chosen from a hydroxycyclohexanyl, an ether, an ester, an amide, an amine, an acid and its salts, a cyano, a thio, a urethane, a urea, a carbonate, a carbamate, a sulfonate, a sulphonomide, a phosphate, or combinations thereof, and X is acrylamide or a polymerizable group selected from the group consisting of substituted or unsubstituted unsaturated aliphatic hydrocarbons, substituted or unsubstituted aromatic hydrocarbons, acrylates, and methacrylates. |
