Laboratory of solution methods

The following activities of this department can serve as examples:

  • ​determination of average relative molecular weights and distribution curves of HDPE, PP and their copolymers by using gel permeation chromatography (GPC) and viscometry
  • viscometric determination of viscosity number and limiting viscosity number of polymers and copolymers in a given solvent and at a certain temperature according to ISO 1628 and ISO 307
  • GPC determination of branched PE: the connection of GPC apparatus with the viscometer detector enables the determination of branching coefficient, branching factor and the distribution of branches in whole range of molecular weights measured
  • determination of structure heterogeneities of PE and PP by the TREF method in analytical and preparative mode
