Title:
PRODUCTION OF RESIN COMPOSITION EXCELLENT IN THERMAL STABILITY
Document Type and Number:
Japanese Patent JP3181702
Kind Code:
B2
Abstract:
PURPOSE: To produce the resin composition excellent in thermal stability and dispersibility by melt-kneading a polyphenylene ether resin with a polyolefin resin by the use of an extruder and subsequently further melt-kneading the first kneaded product with a specific copolymer by the use of a side feeder.
CONSTITUTION: The resin composition comprises (A) 40-94 pts.wt. of a polyphenylene ether resin [preferably poly(2,6-dimethyl-1,4-phenylene ether)] or the polyphenylene ether resin containing a polystyrene resin, (B) 2-20 pts.wt. of a polyolefin resin having a number-average mol.wt. of 30000 or higher (preferably ethylene/propylene copolymer or low density polyethylene), and (C) 4-40 pts.wt. of a vinylic aromatic compound-conjugated dienic compound copolymer (preferably styrene-butadiene copolymer), and/or the hydrogenation product of the copolymer. The components A and B are melt-kneaded with each other by the use of an extruder equipped with a side feeder and subsequently further melt-kneaded with the component C to produce the resin composition excellent in thermal stability and in the dispersibility of the component B.
