Foreword

GB/T 36214 "Plastics volume exclusion chromatography for the determination of the average molecular weight and molecular weight distribution of polymers" is divided into five parts. --- Part 1. General; --- Part 2. Universal Correction Method; --- Part 3. Low temperature method; --- Part 4. High temperature method; --- Part 5. Light scattering method. This part is the first part of GB/T 36214. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This section uses the translation method equivalent to ISO 16014-1.2012 "plastic volume exclusion chromatography to determine the average molecular weight of the polymer And molecular weight distribution Part 1. General. This part was proposed by the China Petroleum and Chemical Industry Federation. This part is under the jurisdiction of the National Plastics Standardization Technical Committee (SAC/TC15).

1 Scope

This part of GB/T 36214 specifies the determination of the average molecular weight and molecular weight distribution of polymers using volume exclusion chromatography (SEC). General method. The average molecular weight and molecular weight distribution are calculated from the calibration curve. The calibration curve is either by GB/T 36214.2~ Calculated from the polymer standard of one of the SEC techniques described in GB/T 36214.4, or equipped with light scattering detection as described in GB/T 36214.5 The absolute molecular weight data of the volume exclusion chromatography (SEC-LS) of the detector was calculated.

3 Terms and definitions

The following terms and definitions defined by ISO 472 apply to this document. 3.1 Volume exclusion chromatography size-exclusionchromatography; SEC The hydrodynamics of molecules eluted in a column packed with a non-absorbent porous material with a pore size similar to the size of the molecule being separated A liquid chromatography with a volume based on separation. Note. The term gel permeation chromatography (GPC) should be used only when the non-absorbent porous filler material is a gel; however, volume exclusion chromatography (SEC) terminology It is preferred. 3.2 Light scattering detection light-scatteringdetection LS detection A technique for determining the quality or size of a polymer molecule by measuring its light scattering. ......
