摘要： Disclosed are materials and compositions effective for the selective removal of gaseous aldehydes from tobacco smoke. The materials and compositions comprise tobacco smoke filters comprising a fibrous material or fibers of a polymeric material containing covalently-bonded acetoacetoxy residues. The fibrous material or fibers are capable of reacting with and removing aldehydes present in tobacco smoke. Also disclosed are processes for the preparation of fibrous materials and fibers of a polymeric material containing covalently-bonded acetoacetoxy residues and methods for the removal of a gaseous aldehyde from tobacco smoke by contacting tobacco smoke with the aforesaid fibrous materials or fibers containing covalently-bonded acetoacetoxy residues.

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.
