    Abstract: High pressure injection apparatus (2) for addition of a liquid formulation into a melt stream comprises a first pump which is arranged to accurately meter the liquid formulation (including highly loaded formulations comprising solids comprising particles of relatively large size) and a second pump which boosts the pressure of the formulation to that of the melt stream into which it is to be injected. In an embodiment, the apparatus includes a tank (4) for initially receiving liquid formulation. The tank is subjected to ambient temperature and pressure and need not be stirred or otherwise agitated. The tank is arranged to deliver the formulation via pipe (6) into a first pump (8) (which may be a diaphragm pump or a progressing cavity pump). The pump is arranged to work at a pressure up to 120 bar to boost pressure. Downstream of pump (8), a pipe (10) is arranged to deliver formulation from the pump (8) to a gear pump (12), driven by a motor (13). The gear pump acts to meter the liquid formulation. In an alternative embodiment, apparatus may include a progressing cavity pump to meter formulation and a gear pump to increase pressure. The apparatus may be used to inject a fluid formulation into a melted polymeric material.

    Abstract translation: 用于将液体制剂添加到熔体流中的高压注射装置（2）包括第一泵，其布置成精确地计量液体制剂（包括包含含有相对大尺寸的颗粒的固体的高负载制剂）和第二泵， 制剂的压力与要注入的熔体流的压力。 在一个实施例中，该装置包括用于初始接收液体制剂的罐（4）。 该罐受到环境温度和压力的影响，不需要搅拌或以其它方式搅拌。 罐被布置成通过管道（6）将制剂输送到第一泵（8）（其可以是隔膜泵或进行空腔泵）。 泵被设置为在高达120巴的压力下工作以增加压力。 在泵（8）的下游，管道（10）布置成将制剂从泵（8）输送到由马达（13）驱动的齿轮泵（12）。 齿轮泵用于测量液体配方。 在替代实施例中，装置可以包括用于计量配方的前进空腔泵和用于增加压力的齿轮泵。 该装置可以用于将流体制剂注入熔融的聚合物材料中。

    Abstract: A method of decreasing aldehyde content in a polymeric material uses a compound (Z) which includes a moiety of formula (I): wherein each R1 and R2 independently represents a substituent, n1 is 0 to 4 and n2 is 0 to 4; wherein X is selected from the group comprising C, N, P, O and S atoms; and each of the two benzene rings includes a moiety formula (A) and a moiety formula (B): NH wherein the carbon atom of moiety (A) and the nitrogen atom of moiety (B) are separated by at least one and not more than two atoms.

    Abstract: 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.
