analytical method and device for characterization of a polymer sample

摘要

ANALYTICAL AND DEVICE METHOD FOR CHARACTERIZATION OF A POLYMER SAMPLE An analytical method comprising making a first fractionation of a polymer sample based on differences in crystallinity to provide a first set of sample fractions, performing a first analysis on the first set of sample fractions by performing a second fractionation of the first set of sample fractions to produce a second set of sample fractions, performing a second analysis on the second set of sample fractions, and synchronizing the first fraction and the second fraction to provide approximately simultaneous analysis of the sample. of polymer.
