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

    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...
