Claim 14:
15. A process of producing an aryl-substituted saccharide or glycoside or a mixture of a plurality of aryl-substituted saccharides or glycosides comprising the steps of:
1) reacting a saccharide or glycoside represented schematically by the following formula (X-1) or formula (X-2), optionally in the presence of a catalyst, to obtain an etherified saccharide or glycoside,, in formula (X-1) and formula (X-2), two R1, same as or different from one another, are each independently selected from the group consisting of hydrogen and C1-20 linear or branched alkyl group, and m is an integer of 1 to 3, wherein the etherifying agent is an alkylene oxide monomer represented schematically by the following formula (A-11), a polyhydroxyl monomer represented schematically by the following formula (A-21) or a combination thereof,, in formula (A-11), Ra is a hydrogen atom or a C1-5 linear or branched alkyl group, and, in formula (A-21), Rb is a C1-4 linear or branched alkylenyl group and X is a hydroxyl group or a halogen atom,
2) reacting the etherified saccharide or glycoside with an arylethylene monomer represented schematically by the following formula (B-11) or formula (B-12), optionally using an acrylamide monomer represented schematically by the following formula (B-21), optionally using a sulfoethylene monomer represented schematically by the following formula (B-31) or formula (B-32), optionally using a siloxyethylene monomer represented schematically by the following formula (B-41) or formula (B-42), and optionally using a carboxyethylene monomer represented schematically by the following formula (B-51) or formula (B-52) for the reaction, to obtain the aryl-substituted saccharide or glycoside or the mixture of a plurality of aryl-substituted saccharides or glycosides,, in formula (B-11), Ar is an optionally substituted C6-20 aryl group,, in formula (B-31) and formula (B-32), L1 is any linking group having no more than 10 carbon atoms and M is hydrogen, alkali metal or ammonium (NH4),, in formula (B-41) and formula (B-42), L2 is any linking group having no more than 10 carbon atoms, and R′ is a C1-4 linear or branched alkyl group,, in formula (B-51) and formula (B-52), L3 is any linking group having no more than 10 carbon atoms, and M is hydrogen, alkali metal, or ammonium (NH4).
