IMPROVEMENT ON PROCESSABILITY OF PPE-POLYSTYRENE ANTISTATIC BLEND BY ADDITION OF STYRENE-ACRYLIC ACID COPOLYMER

摘要

PURPOSE: To obtain the blend having an excellent antistatic property, melt flow performance, etc. by compounding a polyphenylene ether resin, an alkenyl arom. resin copolymerized with an olefinic acid and a specific reforming additive. ;CONSTITUTION: (A) 100 pts.wt. (hereafter pts.) mixture composed of (a) 1 to 99 pts. polyphenylene ether resin [e.g. poly(2,6-dimethyl-1,4-phenylene)ether] and (b) 90 to 1 pts. another thermoplastic polymer (e.g. rubber modified impact resistant PS resin) not contg. the olefinic resin at need, (B) 1.0 to 15.0 pts. alkenyl arom. resin copolymerized with the olefinic acid (e.g. a copolymer of acrylic acid and PS resin) and (C) 1 to 15 pts. at least one kind of the reforming additive [e.g. methyl-octyl-bis(2-hydroxyethyl)ammonium paratoluene sulfonate] which is preferably an antistatic agent and is sucked to the olefinic acid of the component B are mixed.;COPYRIGHT: (C)1989,JPO
