Plastics. Determination of average molecular weight and molecular weight distribution of polymers using size-exclusion chromatography - High-temperature method
What is ISO 16014-4 - Distribution of polymers using SEC at high-temperature method about?
ISO 16014 discusses plastics. ISO 160144 is the fourth part of the ISO 16014 multi-series and discusses determining average molecular weight and molecular weight distribution of polymers using SEC at high-temperature method.
ISO 160144 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 relative method (see ISO 160141 ).
