Cellulose Esters, Inorganic Esters

Abstract

Cellulose esters are cellulose derivatives which result from the esterification of the free hydroxyl groups of cellulose with one or more acids. Cellulose nitrate is the oldest cellulose derivative and the only inorganic ester of commercial importance. Manufacturing and uses of sulfur‐ and phosphorus containing cellulose esters are discussed. An analysis of the oldest and most important inorganic ester of cellulose, cellulose nitrate, is presented.

Special Aspects of Nitrocellulose Molar Mass Determination by Dynamic Light Scattering

“…The dynamic light scattering method is typically used in a wider range of molar masses of polymers. However, the dependencies used in static light scattering are usually implemented to interpret the received scattering intensity data [ 52 , 53 ]. Additionally, before determining the molar mass of the polymer by the dynamic light scattering method, it is required to characterize the viscosity and refractive index of the solvent and polymer solutions by known methods [ 44 ].…”
