Popis: The molecular structure of graft copolymers were determined by the seldom applied but the most informative and the most reliable approach consisting of the comparative study of molecular parameters (diffusion and sedimentation coefficients, intrinsic viscosity, and MW) of the main and side chains and those of the final product. The small number of grafted chains per cellulose derivatives molecule was explained by the degradation of the backbones occurring on exposure to Co3+ ions simultaneously with their initiation. The possible degradation types are discussed.
