  • Polymeric materials
    Patent number: 11124896
    Abstract: Additives such as colourants may be incorporated into polymeric materials such as polyesters, such as in polyester fibre production, by use of a liquid formulation comprising colourant and a vehicle. The vehicle may comprise a functionalised pentaerythritol, trimethylolpropane or trimellitate. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus.
    Type: Grant
    Filed: February 22, 2017
    Date of Patent: September 21, 2021
    Assignee: COLORMATRIX HOLDINGS, INC.

  • POLYMERIC MATERIALS
    Publication number: 20140113997
    Abstract: A method of making a sheet structure comprising a first polycarbonate layer which comprises a UV-absorbing compound and a second polycarbonate layer comprises: (i) selecting a liquid formulation comprising a vehicle, for example a trimellitate or low molecular weight acrylic and an UV absorbing additive; and (ii) mixing the liquid formulation with polycarbonate when said first polymeric material is in a molten state, for example in an extruder.
