Viscosities of solutions of polystyrene in toluene were measured for concentrations up to 400 kg m ~3 at 298 K. Polymers of molecular weights ranging from 8.7 x 103 to 2.4 x 106 were used. It is observed that viscosity of the polymer solution increases with increasing concentration and molecular wei
A detailed rheological study of cellulose nitrate in ethylacetate had been carried out in the dilute concentration (c) regime, covering a degree of polymerization (DP) range between 300 < DPq < 7000 and shear rates ( q ) between 100 s-l < 7 < 2000 s-'. The results show a strong dependence of the tra
