THE USE OF FRICTIONAL COEFFICIENTS TO EVALUATE UNPERTURBED DIMENSIONS IN DILUTE POLYMER SOLUTIONS,

reportActive / Technical Report | Accession Number: AD0618163 | Need Help?

Abstract:

It was shown that the unperturbed dimensions of polymer molecules can be estimated from a knowledge of the frictional coefficients in any given solvent. The method involves a graphical procedure based on a simple relation which is similar to an equation developed by Stockmayer and Fixman relating intrinsic viscosity and molecular weight. The method is tested experimentally using data obtained from dilute solution measurements on polystyrene and polymethylmethacrylate. Author
