Plastics — Determination of average molecular weight and molecular weight distribution of polymers using size-exclusion chromatography — Part 4: High-temperature method
Preview
Summary
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, this test method is classified as a relative method (see ISO 16014-1).
