After mixing with this chitosan or chitosan aqueous solution and the above-mentioned radical polymerizability monomer which dissolve that derivative in acidic aqueous solution

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a chitosan-containing composite emulsion keeping high volume efficiency and having improved quality.;SOLUTION: The polymerization of a radical-polymerizable monomer in the presence of chitosan or its derivative is carried out by continuously or intermittently adding an emulsion liquid of the radical-polymerizable monomer to the reaction system.;COPYRIGHT: (C)2004,JPO
