Plastics. Determination of average molecular weight and molecular weight distribution of polymers using size-exclusion chromatography - Low-temperature method1 Scope 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 test method is classified as a relative method (see
