    Cellulose Acetate Polymer - Paperonweb

    Cellulose acetate polymer is chemically degraded by a process called hydrolysis, which means breaking apart by the addition of water (9). This is a chemical reaction in which water is added to the cellulose acetate polymer causing the release of acetic acid molecules. This process proceeds stepwise until all the acetate groups are released
