Plastics. Determination of average molecular weight and molecular weight distribution of polymers using size-exclusion chromatography - High-temperature methodWhat is this standard about? 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. 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
