PLASTICS – DETERMINATION OF AVERAGE MOLECULAR MASS AND MOLECULAR MASS DISTRIBUTION OF POLYMERS USING SIZE-EXCLUSION CHROMATOGRAPHY -PART 4: HIGH-TEMPERATURE METHOD (ISO 16014-4:2003, IDT)
This Malaysian Standard specifies a method for determining the average molecular mass and the molecular mass distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at temperatures between 60 °C and 180 °C. The average molecular mass and the molecular mass distribution are calculated from a calibration curve constructed using polymer standards. Therefore, this test method is classified as a relative method.
