Particularly, it relates to a resin composition comprising: (A) 70 to 99 parts by weight of a polyphenylene ether resin, and (B) 1 to 30 parts by weight of a liquid-crystal polyester, wherein the polyphenylene ether resin in the composition contains 10 to 30 wt. % of polymer having a molecular weight of 20,000 or less and has a molecular weight distribution (Mw/Mn) of 1.8 to 3.5.Type: ApplicationFiled: March 4, 2002Publication date: December 19, 2002Inventors: Hiroshi Kamo, Shingo Kuga, Takashi Ono, Masanori Ikeda

Patent number: 6489404Abstract: 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.Type: GrantFiled: November 16, 2001Date of Patent: December 3, 2002Assignee: General Electric CompanyInventors: Piet J Bolluijt, Jasper R.
