  • Profile extrusion method with reduced die build-up and extruded article prepared thereby
    Patent number: 8129454
    Abstract: A profile extrusion method utilizes a specific poly(arylene ether)/polystyrene composition with little or no unhydrogenated poly(conjugated diene) rubber. The method substantially reduces the amount of die lip build-up during continuous profile extrusion for eight hours or more. Reduction of die lip build-up in turn improves the structural integrity and aesthetic properties of the extruded article.
    Type: Grant
    Filed: November 25, 2008
    Date of Patent: March 6, 2012
    Assignee: Sabic Innovative Plastics IP B.V.
    Inventors: Johannes E. Fortuyn, Torben Paul Kempers, Vijay R. Mhetar, Kirti Sharma
