  • Patent number: 7053068
    Abstract: By the reaction of chitosan with iminothiolactones such as 2-iminothiolane, thiol groups can be covalently immobilized on the polymer. The resulting chitosan derivatives exhibit thiol groups which are capable of forming inter- and intramolecular disulfide bonds. Because of this crosslinking process the viscosity of polymer solutions is strongly improved. Moreover, the cationic character of the polymer is strongly improved.
