摘要:
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.
