    摘要： A process for the processing of an undried particulate polymer or polymer mixture by means of a single- or multiscrew extruder comprising a barrel comprising one or more screws, a feed section intended for the polymer and provided on the barrel and, provided on the barrel, a melting region in which the polymer or polymer mixture melts, where the undried polymer or polymer mixture introduced by way of the feed section into the barrel is devolatilized in at least one vacuum devolatilization region downstream of the feed section and upstream of the melting region in the barrel.

    摘要： A method of plastic moulding to form a moulded or extruded article, the method employing a moulding apparatus comprising a barrel containing a screw extending between a feed zone supplied by a feed hopper for plastics material, a compression zone and a metering zone for delivery of molten plastics material to a mould or extrusion die, the method comprising introducing into the feed zone a first plastics material (20) and a single body of a second plastics material (22), the first plastics material (20) having a different physical property to the second plastics material and the second plastics material (22) being introduced into the feed zone in a size and a frequency of delivery relative to the flow of the material through the barrel such that the second plastics material (22) is substantially melted and blended with the first plastics material to form a third plastics material with a different physical property to the first or second plastics material across the whole cross sectional area of the metering zone, the molten plastics material delivered to the mould or extrusion die in a predetermined sequence with each plastics material having different physical properties.
