Abstract Cellulose acetate (CDA) cannot be processed as raw material because it starts to decompose before
melting. Triacetin and diacetin were tested to improve CDA processing versus conventional phthalate as
environmentally sustainable plasticizers, because of their low toxicity and fast biodegradability. The addition
of triacetin and diacetin allowed melt processing of CDA and the results of tensile tests outlined their effect
as plasticizers. The values of mechanical properties were compatible with the requirements for applications
in rigid packaging. From the results of biodegradation tests it can be concluded that for pure cellulose
acetate, complete biodegradation was obtained within 200 days of… More >
