Fibre Chemistry Aims and scope

Abstract

It was found that a specific feature of aqueous solutions of Na-CMC and MHPC is the presence of a viscosity extremum for a polymer ratio of 80:20 wt. % and in treating the MHPC solution in a rotary-pulsed activator at the rate of 300 rpm. It was hypothesized that an increase in the size of the coils of the MHPC macromolecules as a result of improvement of the thermodynamic quality of the solvent in the first case and their stretching in the second case is the cause of the increase in the viscosity of the solutions. Films spun from solutions, characterized by anomalous high viscosity values, have high strength and elasticity.
