Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
A polymer comprising siloxanyl main chains from which are pendant alkylene anchoring chains to each of which is bound an anchoring group selected from the group consisting of --SH, alkylsulfides, --CHCH 2 CH 2 SS, thioethers, alkyldisulfides, --Si(CH 3 ) p (A) 3-p , wherein p is 1, 2 or 3 and A is halogen or alkoxy containing 1 to 4 carbon atoms, pyridine, isonitrile, and --COOH, wherein said polymer further comprises a plurality of fluorinated alkyl-capped, fluorinated polyalkoxy side chains, for binding through chemisorption to a solid surface, wherein the polymer is capable upon said binding of forming from solution a self-assembled ultrathin anisotropic film on said surface.
Claim 2
Dependent Claim
109 words
A polymer comprising siloxanyl main chains from which are pendant alkylene anchoring chains to each of which is bound an anchoring group selected from the group consisting of --SH, alkylsulfides, --CHCH 2 CH 2 SS, thioethers, alkyldisulfides, --Si(CH 3 ) p (A) 3-p , wherein p is 1, 2 or 3 and A is halogen or alkoxy containing 1 to 4 carbon atoms, pyridine, isonitrile, and --COOH, wherein said polymer further comprises a plurality of fluorinated alkyl-capped, fluorinated polyalkoxy side chains, for binding through chemisorption to a solid surface, wherein the polymer is capable upon said binding of forming from solution a self-assembled ultrathin anisotropic film on said surface.
Claim 3
Dependent Claim
38 words
A polymer according to claim 1 wherein the siloxanyl main chains are further substituted with at least one substituent, wherein the substituents are the same or different and are selected from the group consisting of hydrogen and methyl.
Claim 4
Dependent Claim
15 words
A polymer according to claim 1 wherein the side chains are perfluoro-alkyl capped, perfluorinated polyalkoxy.
Claim 5
Dependent Claim
15 words
A polymer according to claim 1 wherein the side chains are perfluoromethyl capped, perfluorinated polyalkoxy.
Claim 6
Dependent Claim
70 words
A polymer according to claim 1 wherein said side chains are substituted with one or more functional groups selected from the group consisting of --NH 2 , CH 2 =CHC(O)O--, CH 2 =C(CH 3 )C(O)O--, SF 5 , SO 2 F, --OH, --C(O)OH, --C(O)Cl, --CH=CH 2 , --OC(O)CH 3 , cationic species, anionic species, zwitterionic species, proteins, amino acids, polypeptides, pharmacologically active agents, catalysts, dyes, liquid crystals, antibodies, and antigens.
