Claim:
A support material consisting essentially of a cross-linked polymer compound comprising a radical of general formula (II): —X—Y-A[CH 2 —CH(R)-L-CH(R)—CH 2 ] m A-Y—X— (II) where X represents an oxygen atom or the group —NH, m is an integer other than zero equal at most to 5, R represents a hydrogen atom or a substituted or non-substituted, linear or branched alkyl radical having from 1 to 8 carbon atoms, Y represents a —NH—CO-group, —NH—CS-group or —CO-group, A represents a single bond, a linear or branched alkylene radical having from 1 to 21 carbon atoms, an arylene radical having from 6 to 18 carbon atoms or an aralkylene radical having from 7 to 40 carbon atoms, L represents a bis-sulphoxide radical of general formula (IIIb), or bis-sulphone radical, of general formula (IIIc), or a bis-silane radical of general formula (IV), below: where S represents a sulphur atom, O an oxygen atom and Si a silicon atom and where W 1 and W 3 , identical or different, each represent: a linear or branched alkylene radical having from 1 to 21 carbon atoms, an arylene radical having from 6 to 18 carbon atoms, or an aralkylene radical having from 7 to 40 carbon atoms; W 2 represents a single bond, W 1 , an oxygen atom, a sulphur atom or a symmetrical diester of formula R 5 represents a linear or branched alkyl radical having from 1 to 5 carbon atoms or hydrogen, and R 4 represents the radical where R 6 is (CH 2 ) n2 or oxygen and where n1 varies from 0 to 3000 and n2 from 0 to 10, provided that R 4 is not an oxygen atom, the arylene radicals contained respectively in the radicals of general formula (II) being able to be substituted by one or more atoms or radicals, identical or different, of at least one halogen atom, at least one alkyl radical containing from 1 to 4 carbon atoms, at least one alkoxy radical containing from 1 to 4 carbon atoms or at least one nitro group, wherein the radical of general formulae (II) is bound to at least one osidic chiral unit of a linear, branched or cyclic linkage of a polysaccharide or oligosaccharide derivative according to the general formulae (VIII): where X, Y, A, R, L each have the same meaning as defined above and the chiral unit represents an osidic chiral unit of a linear, branched or cyclic linkage of a polysaccharide or oligosaccharide derivative, wherein “chain i” and “chain j” represent chiral units at each end of the radicals of formula (II), situated as separate chains or separate linkages of osidic units, within the polysaccharide or oligosaccharide, wherein said polymer compound is intermolecularly cross-linked in a tri-dimensional network and therefore is insoluble in polar organic solvent, and optionally containing a mineral or an organic support material.
