Scope: This part of GB/T 36214 specifies the method for determining the average molecular weight and molecular weight distribution of polymers by size exclusion chromatography (SEC) using an organic eluent at 60 °C to 180 °C. The average molecular weight and molecular weight distribution are calculated based on the calibration curve constructed by the polymer standard sample, so this test method is a relative method (see Appendix A and Appendix A of GB/T 36214.1-2018).
