Title:
MODIFIED CELLULOSIC FIBER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3239146
Kind Code:
B2
Abstract:
PURPOSE: To obtain modified cellulosic fiber containing carboxyl group introduced thereinto and a method for producing the modified cellulosic fiber.
CONSTITUTION: This modified cellulosic fiber is characterized by subjecting cellulosic fiber to graft copolymerizing reaction with methacrylic acid and having 5-30wt.% graft ratio of the methacrylic acid to the cellulosic fiber. This method for producing the modified cellulosic fiber is characterized by subjecting the cellulosic fiber to the graft copolymerization with the methacrylic acid in an aqueous solution containing hydrogen peroxide and a ferrous salt.
