Cellulosetriacetaat
Cellulosetriacetaat is a thermoplastic polymer derived from cellulose. It is produced by the esterification of cellulose with acetic anhydride, typically in the presence of a catalyst. This process introduces acetate groups onto the cellulose backbone, altering its properties. Cellulosetriacetaat is known for its good clarity, toughness, and resistance to light and weathering. It is also biodegradable, which is an attractive characteristic for certain applications.
Historically, cellulosetriacetaat was widely used in photographic film bases, replacing flammable cellulose nitrate. Its excellent optical
