Recent experimental investigation of the terminal relaxation in high molecular weight polyisoprenes by dynamic mechanical measurements (C. A. Bero and C. M. Roland, Macromolecules, 29, 1562 (1996)) has found the terminal relaxation times to be more sensitive to changes in temperature for three-arm s
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
