Abstract:
A cross-linked polymer compound in a three-dimensional network, comprising a radical f general formula (I) or (II)â€”Xâ€”Yâ€”A[CH2â€”CH(R)â€”CH(R)â€”CH2]m Aâ€”Yâ€”Xâ€”â€ƒâ€ƒ(I) â€”Xâ€”Yâ€”A[CH2â€”CH(R)â€”Lâ€”CH(R)â€”CH2]m Aâ€”Yâ€”Xâ€”â€ƒâ€ƒ(II) where X represents an oxygen atom of the group â€”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 single bond, â€”NHâ€”COâ€” group, â€”NHâ€”CSâ€” group or â€”COâ€” 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-thioether radical, of general formula (IIIa), 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:â€”Sâ€”W1â€”W2â€”W3â€”Sâ€”â€ƒâ€ƒ(IIIa) where S represents a sulphur atom, O an oxygen atom and Si a silicon atom and whereW1 and W3, 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; W2 represents a single bond, W1 an oxygen atom, a sulphur atom or a symmetrical diester of formula â€ƒR5 represents a line or branched alkyl radical having from 1 to 5 carbon atoms or hydrogen, and R4 represents the radical where R6 is (CH2)n2 or oxygen and where n1 varies from 0 to 3000 and n2 from 0 to 10, the arylene radicals contained respective in the radicals of general formulae (I) and (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 east one nitro group; wherein the radical of general formula (I) or (II) is bound to an osidic chiral unit of a linear, branched or cyclic linkage of a polysaccharide or oligosaccharide derivative according to the general formulae (VII) and (VIII): where X, Y, A, R, L and m each have the same meaning as defined above and the general formula symbol (IX) represents an osidic chiral unit a linear, branched or cyclic linkage of a polysaccharide or oligosaccharide derivative, it being understood that â€œchain iâ€  and â€œchain jâ€  symbolize the fact that the chiral units at each end of the radicals of formulae (I) and (II) are situated on separate chains or separate linkages of osidic units, within the polysaccharide or the oligosaccharide.
