This document provides information on cellulose acetate, including its history, production method, properties, uses, and characteristics. Some key points include: - Cellulose acetate is produced through the reaction of cellulose with acetic acid and acetic anhydride. It can be dissolved and spun into fibers. - It is thermoplastic and soluble in many organic solvents. Fibers are soft, smooth, and resist static cling. - Other cellulose esters include cellulose acetate propionate and butyrate. Mixed esters have varying hydrophobicity. - Viscoelastic behavior is influenced by degree of substitution and solvent system. It can undergo sol-gel transitions.
