Abstract: <PICT:0841808/IV(a)/1> Thermoplastic material containing one or more volatile constituents is extruded from an annular opening into tubular film, vapours of the volatile constituent(s) being released into the interior of the tubular film, and an inert gas is injected into the tubular film at a predetermined distance from the annular opening such that the vapours of the volatile constituent(s) are diluted before their release from the tubular film at a point adjacent to the annular opening, and the rate of entry of inert gas into the tubular film is sufficient to maintain a pressure within the tubular film greater than atmospheric.  Polyvinyl chloride is a specified thermoplastic material, air, nitrogen and carbon dioxide are specified inert gases and dibutyl phthalate is a specified volatile constituent. As shown, a screw extruder 1 feeds a thermoplastic material containing a volatile constituent to an annular opening 2 which comprises a die and mandrel.  Concentric conduits 3, 6 are arranged axially in the mandrel for supply and withdrawal respectively of gas.  Tubular film 5 leaving annular opening 2 is simultaneously expanded and cooled to the desired extent by inert gas entering through conduit 3 and the resultant tubular film 5a is drawn off by pinch rolls 4.  Speedy replacement of gas within tubular film 5a may be effected by connection of a suction pump to withdrawal conduit 6.  Inert gas may be injected into the tubular film at a point distant from the annular opening or may have its temperature adjusted before injection into the tubular film.
