METHOD FOR PREPARING GRAFTED COPOLYMERS OF CHITIN AND CHITOSAN WITH SYNTHETIC POLYMERS Russian patent published in 2007 - IPC C08B37/08 C08F251/02 

Abstract RU 2292354 C1

FIELD: polymers, chemical technology.

SUBSTANCE: invention describes a method for synthesis of grafted copolymers of chitin and chitosan with synthetic polymers. Method involves chemical interaction of chitin or chitosan with a synthetic polymer chosen from the group comprising polyacrylamide, polylactic acid, polyvinyl acetate, polyvinyl alcohol, maleic anhydride-modified polyethylene or polypropylene or with a monomer - acrylamide or lactide (cyclic dimer of lactic acid). The reaction is carried in solid aggregate state of reagents by the reaction extrusion at temperature below melting point of synthetic reagent. Method provides excluding the used of catalysts or solvents.

EFFECT: improved method of synthesis.
