COMPOSITION DISTRIBUTION ANALYTICAL METHOD OF ETHYLENE-NORBORNENE COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a composition distribution analytical method of an ethylene-norbornene copolymer, capable of obtaining composition distribution of ethylene norbornene using temperature gradient interaction chromatography.SOLUTION: A composition distribution analytical method of an ethylene-norbornene copolymer is a method for analyzing composition distribution of the ethylene-norbornene. A column includes a stationary phase composed mainly of graphite. This composition distribution analytical method includes: a filling step (A) of filling a sample solution containing the ethylene-norbornene copolymer into a column; a fixing step (B) of fixing a sample to a stationary phase; and an eluting step (C) of eluting the sample. The eluting step (C) is performed from a predetermined starting temperature to a predetermined end temperature in the temperature gradient which gradually changes the temperature.SELECTED DRAWING: Figure 1
