چکیده
|
Samples of polyethylene oxide having different molecular mass (35,12,6 kg/mol) are investigated with reference to characteristic concentration (cc),critical aggregation concentration (cac) and hydrodynamic radius (r h). using surface tension,light scattering,viscosity and conductance measurement it has been concluded that cc and cac decrease with molecular mass of polymer. the intrinsic viscosity. r h and molecular mass relationship have also been established.
