Abstract
The paper performs a viscometric study of cellulose powder in cupriethylene diamine at different temperatures. The dimensions over a wide range of conc entrations, as well as the dilute-semidilute and semidilute-concentrated cr itical concentrations and the concentration at which the macromolecules att ain their unpertubed dimensions were determined. The perturbed and unpertur bed chain flexibility for cellulose powder, both untreated and treated by a lkaline extraction or by bleaching with H2O2, were discussed.
