  • Patent number: 6465580
    Abstract: 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
