INHERENTLY FLAME RETARDANT COMPOUND TO DIFFUSE VISIBLE LIGHT FROM FIXTURES CONTAINING LIGHT EMITTING DIODES AND PANELS MADE THEREFROM
Visible light actually emitted by a light emitting diode (LED) at a point source is perceived by a viewer of that LED to be sufficiently diffuse to hide the point source. A panel between the LED and the viewer is made from a mixture of polyvinyl halide polymer in a continuous phase and visible light refracting polymeric particles in a discontinuous phase. The polyvinyl halide has a refractive index different from the particles, and both have a different refractive index from air. Optical refraction causes the diffusion, providing "hiding power" to the panel, which is beneficially, inherently flame retardant because of the use of the polyvinyl halide as the continuous phase. Mixtures made with large visible light refracting polymeric particles can cause during profile extrusion randomly uneven surfaces to increase diffusion and reduce gloss.

METHOD OF AND APPARATUS FOR INJECTING A LIQUID FORMULATION INTO A MOLTEN POLYMER
Injector (14) for injecting a liquid formulation into a molten polymer includes outlet (21) at one end and, at its other end, is arranged to be connected to upstream conduit (25) via a coupling housing (26) so that liquid formulation can pass from conduit into the injector, and further includes an elongate conduit (27) in which an elongate pin is slideably arranged being capable of expelling all liquid formulation from conduit. To address the risk the outlet could become blocked in use, whilst avoiding the need to depressurize and/or stop the flow or polymer in extruder (19), the injection apparatus includes a spool (34) which is rotatably mounted within wall (35) of the extruder and is arranged to be rotated about an axis which extends substantially perpendicularly to the elongate extent of the extruder through which a polymer stream (18) flows. The spool may be moved between a first configuration and a second configuration wherein a flow path is interrupted, but wherein molten polymer continues to flow in said polymer flow conduit.

A polymeric melt composition includes a polymeric material and a nucleating agent additive composition. The nucleating agent additive composition includes (a) at least one carbonate or bicarbonate, (b) at least one organic acid or its salt, and (c) at least one desiccant. The polymeric material is unfoamed by the additive composition. The additive composition can induce polymer nucleation, such that the rate of production for polymeric articles made by melt forming processes such as injection molding can be improved, even when the carbonate or bicarbonate is present at only very low levels in the polymeric melt composition from which the polymeric articles are shaped.
