Abstract

Modification of chitosan (Ch) with monomethylolurea has been carried out at diferent temperatures and macromolecules of Ch with different numbers of methylurea actionable functional groups were obtained. The kinetic parameters of the grafting of methylcarbamyl radical onto Ch macromolecules at different temperatures were studied and the rate constants and activation energies of above mentioned processes were determined.
