Verfahren zur Bestimmung der Komponentenverteilung in einem kristallinen Copolymer

A method for fractionating crystalline copolymers to determine solubility distribution as a function of temperature. Fractionation is conducted by passing a solvent through a column containing the crystallized copolymer at an increasing temperature from 6 DEG C to about 120 DEG C. The polymer soluti...

Zusammenfassung:	A method for fractionating crystalline copolymers to determine solubility distribution as a function of temperature. Fractionation is conducted by passing a solvent through a column containing the crystallized copolymer at an increasing temperature from 6 DEG C to about 120 DEG C. The polymer solution exiting the column is analyzed by infrared spectroscopy or NMR to determine the composition distribution of the copolymer.
