MODIFICATION OF CHITOSAN BY GRAFT COPOLYMERIZATION

open access: yesProceedings of the YSU B: Chemical and Biological Sciences, 2021
The interaction of N-monomethylol urea with maleic anhydride is studied. The product of this reaction forms an oligomeric monomer by condensation with chitosan. This oligomeric monomer has a capacity of copolymerization in aqueous media with other soluble monomers such as acrylic acid forming crosslinked water-swelling copolymer.
