... ly to make cine films and X-ray films was made by treating cellulose with dilute nitric acid and mixing the product with camphor (to stabilise the celluloid nitrate). Celluloid was used for a variety of plastic items from spectacle frames to imitations of animal parts such as ivory, and is still used in the manufacture of table-tennis balls and specialised laquers.
Cellulose Ethanoates The process of manufacturing cellulose triethanoate is outlined below: Figure 5
The ester that results from this dissolves in organic solvents, which in turn can be used to make plastics. Alternatively, a process called dry spinning is used; instead of being extruded into an acid bath, the filaments are extruded into the air, resulting in the volatile solvent evaporating from the polymer as it leaves the spinneret.
The cellulose triethanoate in which the polymer chains are n ...
