Patent ID: 7770437

Claim:
A molecule having a structural formula: X 1 —(CH 2 ) c —O—([CH 2 ] t —CH 2 —O) n —R 1 —S—X 2 wherein: X 2 is selected from the group consisting of —H and —S—R 5 ; R 5 is an organic spacer selected from the group consisting of —R 2 —(O—CH 2 —[CH 2 ] t ) n —O—(CH 2 ) c —X 1 ′ and —R 3 —(O—CH 2 —[CH 2 ] t ) n —Y 1 ; t is 1 or 2; c is an integer from 0 to 3; n is an integer from 3 to 15,000; R 1 , R 2 and R 3 are each independently a saturated or ethylenically unsaturated hydrocarbyl group having from 3 to 30 carbon atoms, wherein the hydrocarbyl group is independently selected from the group consisting of alkyl, alkenyl, cycloalkyl, cycloalkyl-alkyl, cycloalkenyl, cycloalkenylalkyl, and cycloalkylalkenyl, wherein the hydrocarbyl group is independently unsubstituted or substituted with at least one substituent selected from the group consisting of a heteroatom in a main chain and an oxo substituent, wherein the heteroatom is independently selected from the group consisting of nitrogen, oxygen and sulfur; Y 1 is selected from the group consisting of hydroxy and methoxy; X 1 is selected from the group consisting of fluorophenyl, fluorobenzoyl, fluorophenoxycarbonyl, nitrophenoxycarbonyl, sulfonyl halide, isothiocyanato, isocyanato, carbonyl halide, haloalkylcarbonyl, and diazonium carbonyl; and X 1 ′ is selected from the group consisting of fluorophenyl, fluorobenzoyl, fluorophenoxycarbonyl, nitrophenoxycarbonyl, oxiranyl, aziridinyl, C 2-12 alkenyl, imino- ether, dichlorotriazinyl, sulfonyl halide, alkoxycarbonyl, isothiocyanato, isocyanato, carbonyl halide, haloalklcarbonyl, carboxlic acid anhydride, diazonium carbonyl N-(2- oxotetrahydro-3-thienyl) amido, and N-carboxy-thiazolidinl-2-thione.
