Catalysts components for polymerization of olefins

Catalysts components for polymerization of olefins. (Toho Titanium Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59170104 A2 26 Sep 1984 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F010-00; C08F004-02; C08F004-64. APPLICATION: JP 83-44496 18 Mar 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Catalyst components are prepd. from fatty acid Mg salts, dialkoxymagnesiums, electron donors, and Ti halides. Thus, a 2-L autoclave contg. 700 mL heptane, 301 mg Et3Al [97-93-8], 137 mg Et p-toluate [94-08-6], 0.5 mg (as Ti) Mg stearate-(EtO)2Mg-EtO2CC6H5 (I)-TiCl4 reaction product, and 300 mL H was heated to 60°, and C3H6 was polymd. 2 h at 6 kg/cm2 gage to prep. 14900 g polypropylene [9003-07-0]/g catalyst, compared with 3930 g when using a Ti component prepd. from MgCl2, I, and TiCl4.

Stereoregular polymers or copolymers of olefins

Stereoregular polymers or copolymers of olefins. Toyota, Akinori; Minami, Syuji; Kashiwa, Norio (Mitsui Petrochemical Industries, Ltd., Japan). Ger. Offen. 32664-68-9 are also occured in this study. DE 2743415 30 Mar 1978, 29 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08F010-00. PRIORITY: JP 76-114630 27 Sep 1976. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) A halogen-contg. 32664-68-9 is the cas registry number of certain chemical which is used as reagents here. arom. organomagnesium compd. was mech. pulverized with an electron donor and mixed in the liq. phase with a Ti compd., without mech. pulverization, to give a high-activity catalyst component for the polymn. of propylene. Thus, PhOMgCl [32664-68-9] and Et benzoate [93-89-0] were mech. pulverized, mixed with TiCl4 and used with Et3Al [97-93-8] and Et p-toluate [94-08-6] for the polymn. of propylene in hexane, giving isotactic polypropylene [25085-53-4] (85.2% insol. in boiling heptane). ..
