A functional polymer having active and stable functional groups, for separation or reactive processes in chemical manufacture or analysis, has carbon-linked functional groups on dimethylene spacers; a method of preparation is from pre-existing polymers comprising polymeric 1-(vinylphenyl)ethylene repeat units, by treating with H-X in the presence of free radicals, wherein X comprises a carbon atom that is linked to the -CH[Ph-CH2CH2-]-CH2- remainder of said -CH[Ph-CH2CH2-X]-CH2- repeat unit in said product as a consequence of said reaction; the carbon atom can have characteristics selected from being sp2-hybridized and doubly bonded to an oxygen, being sp3-hybridized and singly bonded to an oxygen, being sp3-hybridized and singly bonded to a nitrogen that is also singly bonded to an sp2-hybridized carbon, being sp3-hybridized and singly bonded to a nitrogen and also to an sp2-hybridized carbon, and being sp3-hybridized and singly bonded to two sp2-hybridized carbons; H-X may comprise an N-alkylamide, N-alkyl urea, crown ether, aza crown ether, polyethylene glycol, N-alkyl amidine, amino acid residue, 1,3-diketone, 1,3-diester, or combinations thereof; H-X may be N-methyl pyrrolidinone, dimethyl acetamide, tetramethylurea, N,N'-dimethylpropyleneurea, 1,8-diazabicyclo[5.4.0]undec-7-ene, 2,4-pentanedione, diethylmalonate, 18-crown-6, dicyclohexano-18-crown-6, polyethyleneglycol methyl ether 350 g/mol, 2-chloroethyl ether, 2-hydroxyethyl ether, N-methylmorpholine or N-acetyl leucine; functional groups are afforded that comprise ether, polyether, crown ether, cryptand, lariat ether, amide, urea, amidine, ester, amine, carboxylic acid, or combinations thereof.
