Project: Characterization of polyelectrolytes in aqueous solution by GPC, light scattering, viscometry, ultracentrifuge or similar methods

Number: 422/2/98
Start: 01 January 1998
End: 31 December 2001

Objective

This is a round robin test (RRT) on polyacrylic acid. The first round has been finished; measurements were by SEC/GPC, light scattering, ultracentrifuge and viscometry. Two samples were characterized in 13 labs. The data scatter is enormous and standardization is necessary in the second stage of the RRT.

Progress
  • First round is finished and the publication is under preparation.
This project was presented at a poster session at the IUPAC Congress/GA July 2001
