    The influence of storage conditions and packaging on acetic acid generation in cellulose acetate fibers

    TATUM C.E.; WILSON S.A.; CASPER R.G.; PEARCE M.J.
    Eastman Chemical Company, Kingsport, TN, U.S.A.
    The cellulose acetate polymer used in cigarette filters is made by acetylating wood pulp with acetic anhydride. One advantage of this modified natural polymer is that it readily degrades by multiple mechanisms. While the ultimate products are carbon ...

    Photodegradability testing of cellulose acetate filters – outdoor weathering vs. accelerated weathering

    STEACH J.K.; FISHER JONES D.
    Eastman Chemical Company, Kingsport, TN, USA
    Degradation testing in the laboratory is based on understanding a material’s exposure to specific environmental forces, which can play a key role in the mechanisms of degradation. Cellulose acetate filters can be degraded by various environmental forces, ...
