PURPOSE: An aqueous solution of soluble chitin derivative containing a diluent and a pore-size controller is treated with an acylating agent to produce title formed product with high exclusion limit, uniform and adjustable pore size and high performance and strength. n CONSTITUTION: (A) An aqueous solution of soluble chitin derivative such as chitin, carboxymethylchitin is combined with (B) a diluent such as alcohol of 4 or less carbon atoms, pyridine or a compound of the formula (R, R' is are 1W4C alkyl; n is 1W3), (C) a pore-size controller such as benzene, toluene or xylene and (D) a surfactant. Then, they are treated with (E) an acylating agent such as organic acid anhydride containing a surfactant and, when necessary, crosslinked. n USE: Filler for chromatography, base material for immobilization of enzyme. n COPYRIGHT: (C)1981,JPO&Japio |
