Notes:
Cellulose 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.
