METHOD FOR QUANTITATIVE ANALYSIS OF SORBITOL COMPOUND IN POLYOLEFIN

摘要

PROBLEM TO BE SOLVED: To provide a method which can efficiently extract a sorbitol compound included in a polyolefin at a high extraction rate.SOLUTION: According to the method, an extraction solvent comprising one or more solvents with a SP value of 8-11, a relative dielectric constant of 7-30 and a boiling point of 100°C or less is impregnated with a polyolefin sample, and ultrasound solvent extraction is conducted with the temperature range of the extraction solvent of 40-70°C, in order for quantitative analysis of a sorbitol compound included in a polyolefin.
