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 radical copolymers of divinylbenzene, by treating with HX(O)mR<1>nR<2> in the presence of free radicals; another method of preparation is by treating a polymer comprising repeat units of the form -CH[Ph-CH2CH2-X(O)mR<1>nR<2>]-CH2- 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-CH2CH2-X(O)mR<1>nR<2>]-CH2- with other substituents; other functional groups may be present; the functional polymer comprises repeat units of the form -CH[Ph-CH2CH2-X(O)mR<1>nR<2>]-CH2-, 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>, NH2, NHR<3>, NR<3>R<4> and NR<5>R<6>, and R<2> may be Cl, Br, O<->, OH, OR<7>, NH2, 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>, R<9> and R<10> are selected from cyclic -(CH2)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.
