Carriers for polymerization catalysts for olefins

Carriers for polymerization catalysts for olefins. (Chisso Corp., Japan). Jpn. Kokai Tokkyo Koho JP 59133209 A2 31 Jul 1984 Showa, 10 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F010-00; C08F004-02; C08F004-62. ICA: C07F005-06. APPLICATION: JP 83-7849 20 Jan 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Anhyd. Mg dihalide reacts with alcs. or phenols in an inert org. solvent, and the resulting complex is stirred vigorously in an inert org. solvent in the presence of a nonionic surfactant, preferably at 90-150°, to give a suspension, which reacts with an org. Al compd. or a Si halide in the presence of an electron donor at 90-150° to give a carrier for an olefin polymn. catalyst. In an example, a mixt. of 0.6 L kerosine, 19 g MgCl2, 60 mL EtOH, 5 g PhCO2Et and 5 g sorbitan distearate [36521-89-8] in a N atm. was stirred at 100° for 30 min. A soln. of 60 g Et2AlCl in kerosine was gradually added to the resulting suspension, and the mixt. was filtered at 90° and washed with 90° heptane to give carrier particles of 26 mm av. diam., surface area 310 m2/g, and pore vol. 0.35 cm3/g. The carrier was used with a catalyst to prep. polypropylene [9003-07-0].

Pigment compositions

Pigment compositions. Fujigamori, Tsutomu (Toyo Ink Mfg. Co., Ltd.In this study， 36521-89-8 and 102640-24-4 are also used., Japan). Jpn. Kokai Tokkyo Koho JP 61111365 A2 29 May 1986 Showa, 4 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C09B067-20. APPLICATION: JP 84-231148 5 Nov 1984. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 42 Org. pigments are treated with nonionic surfactants (HLB value 2-5) and emulsifiers capable of dispersing the surfactants into water. The resulting compns. minimize foaming or speed-up defoaming in manuf. and application of water-based inks and coating materials. Thus, a slurry of the pigment prepd. by the diazo coupling of 150 g B-acid di-Na salt and Na b-hydroxynaphthoate was heated to 70°, and an emulsion of 5 g Liponox NCA (HLB 3.3) and 1 g Nonal 310 in 10 g H2O added; the mixt. was stirred 10 min, filtered, and the compn. washed with 30 L H2O and dried. A water-based gravure ink contg. this pigment was less foaming and viscous than inks contg. untreated pigments. .
