摘要: A tetrafluoroethylene polymer or copolymer suitable e.g. for extrusion on to wire to give an insulated conductor is produced using a dual catalyst system. The first catalyst component is a catalyst giving a high molecular weight (low SSG) such as ammonium persulphate (APS). The second component is a dibasic acid peroxide e.g. disuccinic acid peroxide (DSAP) which is added after the polymerisation has reached 20% conversion. The latter catalyst is found to produce a copolymer powder which can be extruded on to wire to give faultfree coating.

摘要: The invention relates to a smoking article (1) having a high proportion of non-combustible, inorganic material and a relatively low level of visible sidestream. The smoking article comprises a substantially non-combustible, wrapper (5) which extends along the full length of the smoking material rod and enwraps a combustible fuel source (6) and aerosol generating means (7), both of which extend substantially along the length of the smoking material rod. Various suitable fuel source system and aerosol generating systems are described. The article has a visible burn line which advances along the article and produces an ash which can be removed by the smoker in the normal way.
