Determination of Chemical Composition of Polymers by Sec with Coupled Density and Ri Detection. I. Polyethylene Glycol and Polypropylene Glycol

摘要

It is shown, that the chemical composition of copolymers and polymer blends can be determined for any point of the molecular weight distribution using size exclusion chromatography (SEC) with two universal detectors: a density detector and a RI detector.
