    Abstract: The present invention relates to processes for making compatibilized high aspect ratio barrier additives and polymer compositions that comprise compatibilized high aspect ratio barrier additives. The invention also relates to compositions produced by these processes, and articles formed from polymer compositions of this invention. The barrier additives provide passive barriers to gas molecules such as oxygen and carbon dioxide minimizing transit of such molecules through sidewalls of polymer articles containing the barrier additives.

    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: High pressure injection apparatus 2 for addition of a liquid formulation into a polymer melt stream at position 4 comprises pump assembly 6 upstream of an injector assembly 8. Pump assembly 6 is arranged to increase the pressure of the liquid formulation to a high pressure (e.g. up to 400 bar) and to accurately meter the liquid formulation to the injector assembly 8 which is arranged to inject the liquid formulation into the polymer melt stream. The polymer melt may be spun, for example to produce Fully Drawn Yarn (FDY) or Partial Orientated Yarn (POY). The pump assembly 6 comprises a syringe pump 12 which comprises a tube 14 in which a piston 16 is slideably received and is arranged to urge liquid formulation 18 within the tube to an outlet 20 which is coupled to an inlet of injector assembly 8.

    Abstract: Apparatus (2) includes a platform (14) on which is supported, via spaced apart posts (16), a stationary rigid support disc (17). Between the platform (14) and disc (17), plaque holder (18) is rotatably mounted. The plaque holder is arranged to hold a plaque (19) for assessment. The plaque is made by injection moulding from a composition comprising a polymeric material and a specific amount of reheat additive(s) and any other additives(s) to be assessed. The plaque holder is arranged to move the plaque relative to the disc (17). In an input position, the plaque holder (18) is arranged directly underneath opening (20). In a measurement position, which is 90° from the input position, there are provided first and second temperature measuring assemblies (24, 26) arranged to measure the temperature of the top and bottom surfaces of a plaque held in the plaque holder. The plaque holder can be rotated through 90° from the measurement position to a heating position, wherein the plaque is positioned directly below a heat lamp. In use, the plaque holder is rotated to the heating position, wherein the plaque is heated by the lamp for a predetermined time. Then the plaque holder is rapidly rotated back to the measurement position, wherein the temperatures of the upper and lower surfaces of the plaque are rapidly measured. These steps are repeated and data recorded to allow reheat and/or other characteristics of the plaque to be assessed over time.
