  • Thermophysical properties

This platform brings together complementary equipment located in four of the research department laboratories and whose objective is the characterization of the structure and properties of polymers.

The available techniques enable different aspects to be addressed depending on the applications targeted.

Structural characterization:

  • Chemical structure :
  • Molar mass distribution :
      • steric exclusion chromatography (LCPM, LERMaB)
  • Average molar mass :
      • capillary viscometry (LCPM)

 

Solution characterization :

  • Conformation, dimensions :
      • dynamic light scattering (LCPM)
      • capillary viscometry (LCPM)
    •
