Kind Code: A1 A novel cationic polymerization based on carbohydrates that can be easily produced in high yield and high purity and is stable in both acidic and alkaline pH ranges. Of reactive monomers. The monomer has the formula I [Wherein R 1 is a deoxysaccharide having 1 to 20 monomer units, R 2 has the same meaning as R 1 or a C 1 to C 20 -alkyl group, a C 2 to C 20 -alkenyl group , C 1 -C 4 -hydroxyalkyl groups, C 1 -C 4- alkylphenyl groups or in each case 1 to Is a polyoxyethylene-, polyoxypropylene- or polyethyleneimine group having 10 ethylene oxide, propylene oxide or ethyleneimine units, R 3 , R 4 and R 5 are hydrogen atoms or methyl groups and X is a halogen atom. , Tosylate-ion or arylsulfate-ion. ] It is a cationic unsaturated saccharide represented by these. |
