摘要： A cigarette smoking article includes a tobacco rod and a dual filter comprising a tobacco rod end segment made of cellulose acetate tow and a mouth end segment made of a gathered, perforated polymeric film blended with a whitener to produce a substantially non-staining mouth end surface. The polymeric film may also comprise a coextruded flavor film with a flavor carrier layer disposed between a pair of barrier layers for releasing a flavorant into the mainstream smoke during smoking of the cigarette. Transparent wraps may be used to construct the cigarette from the component parts so that the filtration surfaces of the filter rod are visible through the wraps.

摘要： .alpha.-Olefins are polymerized in the presence of Ziegler-Natta catalysts which are polymer supported compounds or complexes of elements of the d-block transition metals, lanthanide or actinide series. An example of the polymer support is chloromethylated polystyrene-divinyl benzene copolymer covalently bonded to catechol. An example of the compound or complex of an element of the transition metal, lanthanide or actinide series is that which results when catechol which is covalently bonded to the polymer is contacted with titanium tetraisopropoxide.
