    摘要： Degradable cellulose esters are disclosed that have incorporated therein or thereon mixed-phase titanium dioxide particles. The esters may be in the form of filters prepared by applying a plasticizer, having the mixed-phase titanium dioxide particles dispersed therein, to cellulose ester fibers to obtain plasticized cellulose ester fibers; and thereafter forming the plasticized cellulose ester fibers into a filter. Alternatively, the particles may be added to the dope from which the fibers are spun, or blended with a cellulose ester intended for molded articles.

    摘要： Degradable filters are disclosed, as well as methods of making them, that include the steps of applying a plasticizer containing a photoactive agent to cellulose ester fibers to obtain plasticized cellulose ester fibers; and forming the plasticized cellulose ester fibers into a filter. The cellulose ester fibers may comprise cellulose acetate, the plasticizer may be triacetin, and the photoactive agent may include a number of types of titanium dioxide, for example mixed phase titanium dioxide particles. The filters are useful, for example, in preparing cigarette filters.
