Overview of polymer parameters monitored with NIRS

Spectroscopy is a versatile method that can be used for a variety of chemical and physical parameters:

 

Feedstock analysis
Polymerization monitoring
Physical properties
  • Hydroxyl number
  • Acid, amine value
  • Identification of materials
    (e.g., HDPE/LDPE)
  • Reaction endpoint determination
  • Moisture content
  • Molecular weight
  • Degree of branching
  • Tacticity
  • Melting point
  • Particle size verification
  • Density
  • Viscosity
