Abstract
Abstract Polymers which form ultrathin, chemically adherent, anisotropic films on substrate surfaces impart useful properties to the surface. The polymers can be functionalized with any of a wide array of side chains and groups to impart properties and/or uses to the substrate.

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.
