The biopolymer chitosan was chemically modified by grafting polyacrylamide or polyacrylic acid in a homogeneous aqueous phase using potassium persulfate (KPS) as redox initiator system in the presence of N,N-methylene-bi ...

The interaction of copper ions with chitosan and three synthesized derivatives with different chelating centers, N-benzylidene chitosan, N-benzyl chitosan and poly-N-(4-(4-R-methoxyphenyl) diazenyl)benzyl-chitosan using ...

Transparent lithium-ion conducting films were prepared by adding lithium perchlorate to a mixture of chitosane (CHI) and poly(aminopropylsiloxane) (pAPS) in a molar ratio 0.6:1 by sol /gel methods. The morphological and ...

New poly(azo) amino-chitosan compounds were obtained from the azo coupling reaction of N-benzyl chitosan and diazonium salts. The thermal behavior of these compounds was studied by thermogravimetric analysis (TG), differential ...
