Concentration-dependence of Solution Viscosity of Branched Polymer
Abstract:
The concentration-dependence of the reduced viscosity of dilute polymer solution is interpreted in the light of the self-association concept of polymer chain in solution.The molar selfassociation constant (Ka) is directly proportional to the effective hydrodynamic volume of the polymer chain in solution.In the sense of self-association or cluster formation of polymer chain in solution, there is no difference between branched and linear polymers.
