Plastics — Determination of average molecular weight and molecular weight distribution of polymers u...
This document specifies a method for determining the average molecular weight and the molecular weight distribution of polymers using size-exclusion chromatography (SEC). The average molecular weight and the molecular weight distribution are calculated using a universal calibration curve instead of the conventional calibration curve.
NOTE This test method is classified as a relative method…
Plastics — Determination of average molecular weight and molecular weight distribution of polymers u...
This document specifies a method for determining the average molecular weight and the molecular weight distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at a temperature lower than 60 °C (see Annex A). The average molecular weight and the molecular weight distribution are calculated from a calibration curve prepared using polymer standards. Therefore, this…

This document specifies a method for determining the average molecular weight and the molecular weight distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at temperatures between 60 °C and 220 °C (see Annex A). The average molecular weight and the molecular weight distribution are calculated from a calibration curve prepared using polymer standards. Therefore,…
Plastics — Determination of average molecular weight and molecular weight distribution of polymers u...
This document specifies a general method for determining the average molecular weight and the molecular weight distribution of polymers using SEC-LS, i.e. size-exclusion chromatography coupled with light-scattering detection. The average molecular weight and the molecular weight distribution are calculated from molecular weight data and weight concentrations determined continuously with elution…
