Electrically conductive resin compositions containing carbon

Electrically conductive resin compositions containing carbon. Ueki, Toru; Sakata, Kenji; Yoshimura, Masaji; Kanezaki, Kazuharu; Takiguchi, Minoru (Mitsui Toatsu Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 03290462 A2 20 Dec 1991 Heisei, 5 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C08L071-12.There are some reagents with their cas registry numbers 86293-61-0 and 16898-52-5 are used in this study. ICS: C08K003-04; C08L025-18; C08L035-00; C08L071-12; H01B001-24. APPLICATION: JP 90-92307 9 Apr 1990. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title compns. contain 50-95% poly(phenylene ether). 5-50% copolymers of styrene with a,b-unsatd. dicarboxylic acid imides, 5-30 phr elec. conductive carbon, and 0.1-20 phr 1,3-di(4-piperidyl)propane (I). Thus, a blend of 98% poly(phenylene ether) with 10% styrene-N-methylmaleimide copolymer (II) was kneaded with 10 parts Ketjen black EC and 5 parts I, pelletized, and injection molded to prep. test pieces having surface resistance 105 W. A compn. contg. no II had poor fluidity and was not moldable. .

Melt-processing aid for polyoxyphenylenes or their blends

Melt-processing aid for polyoxyphenylenes or their blends. Ueki, Toru; Yoshimura, Masaji; Sato, Takashi; Kishi, Susumu (Mitsui Toatsu Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 03285950 A2 17 Dec 1991 Heisei, 4 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C08L071-12. ICS: C08L025-04; C08L071-12. APPLICATION: JP 90-84844 2 Apr 1990. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title aid is 1,3-di(4-piperidyl)propane (I) and is used at 0.1-20 phr based on resins for lowering melt viscosity. Thus, kneading 100 parts polyoxyphenylene with 0.5 part I, and pelletizing gave pellets which had melt flow index 2 g/10 min and gave injection test pieces with heat distortion temp. 170°, vs. 0.4 (difficult to process) and 175, resp. for 0.05 part (instead of 0.5) I.Except for chemicals metioned above, 9003-53-6 and 16898-52-5 are also used. .
