1) (25 points) The molecular weight of a polymer can be determined from its viscosity by the following relationship where [n] is the intrinsic viscosity of the polymer M, is the viscosity averaged molecular weight, and K and a are constants specific for the polymer. The intrinsic viscosity is determined experimentally be determining the efflux time, or the time it takes for the polymer solution to flow between two etched lines in a capillary viscometer, at several different concentrations of...
