Patent ID: 8889163

Claim:
A polymer or oligomer of formula I wherein: A and B are o- or m-phenylene wherein one of A or B is substituted with a polar (P) group and a nonpolar (NP) group and the other of A or B is substituted with neither a polar (P) group nor a nonpolar (NP) group; s is C≡C—; R 1 is (i) halo and R 2 is hydrogen; or (ii)C-s-B-s- and R 2 is C; or, (iii)C-s- and R 2 is -A-s-C wherein C is pyridine or phenyl said pyridine or phenyl optionally substituted with 1 or 2 substituents independently selected from the group consisting of halo, nitro, cyano, C 1 -C 6 alkoxy, C 1 -C 6 alkoxycarbonyl, and benzyloxycarbonyl; NP is a nonpolar group independently selected from R 4 or —U—(CH 2 ) p —R 4 wherein R 4 is selected from the group consisting of hydrogen, C 1 -C 10 alkyl, C 3 -C 18 branched alkyl, C 3 -C 8 cycloalkyl, monocyclic or polycyclic phenyl optionally substituted with one or more C 1 -C 4 alkyl or halo groups, and monocyclic or polycyclic heteroaryl optionally substituted with one or more C 1 -C 4 alkyl or halo groups, and U and p are as defined below; P is a polar group selected from the group consisting of III, hydroxyethoxymethyl, methoxyethoxymethyl and polyoxyethylene —U—(CH 2 ) p —V (III) wherein: U is absent or selected from the group consisting of O, S, S(═O), S(═O) 2 , NH, —C(═O)O—, —C(═O)NH—, —C(═O)S—, —C(═S)NH—, —S(═O) 2 NH—, and C(═NO—) wherein groups with two chemically nonequivalent termini can adopt both possible orientations; V is selected from the group consisting of amino, hydroxyl, C 1 -C 6 alkylamino, C 1 -C 6 dialkylamino, NH(CH 2 ) p NH 2 , N(CH 2 CH 2 NH 2 ) 2 , amidine, guanidine, semicarbazone, basic heterocycle, and phenyl optionally substituted with an amino, C 1 -C 6 alkylamino, C 1 -C 6 dialkylamino and lower acylamino optionally substituted with one or more amino, lower alkylamino or lower dialkylamino; and the alkylene chain is optionally substituted with an amino or hydroxyl group or unsaturated; p is independently 0 to 8; and, m is 2 to about 500.
