发明名称 Reduction of carbonized particles
摘要 The above described deficiencies and drawbacks are overcome by the process for making poly(arylene ether)-polyamide compositions which comprise about 10 weight percent (wt %) to about 90 wt % poly(arylene ether), about 90 wt % to about 10 wt % polyamide, about 0.01 wt % to about 10 wt % compatibility modifier, and optionally other additives known in the art. The process comprises several components which can be employed singly or in combination, namely: utilizing resins and additives that are substantially free of gaseous oxygen (air-free; e.g. less than about 1.0 vol % oxygen preferred, and less than about 0.5 vol % oxygen especially preferred, and less than about 0.05 vol % especially preferred); melting and compounding under an atmosphere which is substantially air-free; adding up to 20 wt % of polyamide to the poly(arylene ether) before compounding; when employing an extruder with an atmospheric vent, operating with the atmospheric vent open; and performing the injection molding under an inert atmosphere.
