Cellulose Acetate Crown Form

 · Cellulose acetate (CA) is a cellulose derivative obtained by replacing the hydroxyl groups from the anhydroglucose units with acetyl groups by means of ester substitution [7], [8]. Compared to pure cellulose, CA has a good solubility in organic solvents, which ensures it a high processability and a wide range of applications.

The most common form of cellulose acetate fiber has an acetate group on approximately two of every three hydroxyls This cellulose diacetate is known as secondary acetate or simply as acetate After it is formed cellulose acetate is dissolved in acetone forming a viscous solution for extrusion through spinnerets which resemble a shower
