| titleOfInvention | Functional polymers bearing non-metal oxyacid derivatives on dimethylene spaces |
| abstract | A functional polymer having active and stable functional groups, for separation or reactive processes in chemical manufacture or analysis, bears nonmetal oxyacid derivatives on dimethylene spacers; a method of preparation is from pre-existing polymers comprising polymeric 1 -(vinylphenyl)ethylene repeat units, including radial copolymers of divinylbenzene, by treating with HX(O) m R 1 n R 2 in presence of free radicals; another method of preparation is by treating a polymer comprising repeat units of the form —CH[Ph—CH 2 CH 2 —X(O) m R 1 n R 2 ]—CH 2 — where X is of lower oxidation state, with oxidizing agent so as to oxidize X to a higher oxidation state; another method of preparation is to exchange one or both of R 1 and R 2 substituents in —CH[Ph—CH 2 CH 2 —X(O) m R 1 n R 2 ]—CH 2 — with other substituents; other functional groups may be present; the functional polymer comprises repeat units of the form —CH[Ph—CH 2 CH 2 —X(O) m R 1 n R 2 ]—CH 2 —, in which X may be S with m= 2 and n= 0, or P with m= 1 and n= 1, R 1 may be Cl, Br, O—, OH, R 3 , OR 3 , NH 2 , NHR 3 , NR 3 R 4 and NR 5 R 6 , and R 2 may be Cl, Br, O—, OH, OR 7 , NH 2 , NHR 7 , NR 7 R 8 and NR 9 R 10 , wherein R 3 , R 4 , R 7 , and R 8 are selected from methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, s-butyl, t-butyl, 2 -ethylhexyl, hexadecyl, 2 -chloroethyl, 2 -bromoethyl, 2,2,2 -trifluoroethyl, 2 -hydroxyethyl, 2 -butoxyethyl, 2 -aminoethyl, cyclohexyl, phenyl, benzyl, 4 -nitrobenzyl, tolyl, a polypeptide, a polysaccharide and a polynucleotide, and R 5 , R 6 , and R 9 and R 10 are selected from cyclic —(CH 2 ) q — wherein q is selected from 2 to 5 ; polymer-bound functional groups are afforded that are sulfonic acid, sulfonate salt, sulfonate ester, sulfonamide, sulfonyl halide, phosphonic acid, phosphonate salt, phosphonyl halide, phosphonate ester or phosphonamide, or combinations thereof. |
