Abstract
AbstractCellulose nitrates with nitrogen contents in the range 11,2 to 13,3 mol‐% are characterized with gel permeation chromatography (GPC) using various detectors, membrane osmometry, static low angle laser light scattering (LALLS) and solution viscosity measurements. The molecular weight data from GPC‐LALLS are generally in good agreement with those obtained by static LALLS and membrane osmometry. GPC‐infrared is used to analyze the nitrogen content. These techniques are also used to characterize cellulose nitrate in propellants. A comparison between two different column packings in GPC‐LALLS analysis is integrated into this study.
