Transition metal compounds and olefin polymerization catalysts containing them

Transition metal compounds and olefin polymerization catalysts containing them. Candlin, John P.; Williams, Ian Gabriel; Caunt, Anthony D. (Imperial Chemical Industries Ltd.In this study， 7778-06-5 and 102-82-9 are also used., Engl.). Ger. Offen. DE 2623720 9 Dec 1976, 67 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08F010-00. PRIORITY: GB 75-23335 28 May 1975. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) TiCl3 was milled with AlCl3, TiCl4, and a Lewis base, such as 2-dimethylamino-1,3-dimethyl-1,3,2-diazaphospholidine 2-oxide (I) [7778-06-5], (Me2N)3PO [680-31-9], Me2NCH2CH2NMe2 [110-18-9], or Ph2SO2 [127-63-9], to prep. polymn. catalysts which were used for the prepn. of polypropylene (II) [9003-07-0] with high mol. wt. and high flexural modulus. Thus, 20 g TiCl3 was milled with TiCl4 10, AlCl3 10, and I 25 mole%/g-atom Ti in the TiCl3, and the catalyst was used to prep. 69.5 g II/mmole TiCl3. .

Cationic water-soluble amine-epichlorohydrin polycondensates

Cationic water-soluble amine-epichlorohydrin polycondensates. Buckman, John D.; Buckman, Stanley J.; Mercer, Gerald D.; Pera, John D. (Buckman Laboratories, Inc., USA). Ger. Offen. DE 2616220 28 Oct 1976, 40 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08G059-10. PRIORITY: US 75-568066 14 Apr 1975. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 36, 63 The reaction of epichlorohydrin (I) [106-89-8] with MeNH2 [74-89-5], BuNH2 [109-73-9], or a similar primary amine and subsequent reaction with a tertiary amine such as Me2NCH2CH2NMe2 (II) [110-18-9] gave polycondensates which were useful as retention aids in papermaking, flocculating agents, algicides, bactericides, dyeing aids for textiles, etc. Thus, 34 kg 50% aq. MeNH2 in 95.3 kg MeOH was treated slowly at 20-40.degree. with 101.5 kg I to prep. partially polymd. bis(3-chloro-2-hydroxypropyl)methylamine which (111 kg MeOH soln. contg. 51.4% polycondensate) was distd. in vacuo to remove 40.8 kg MeOH, mixed with 24 kg water and 46.7 kg aq.There are some commonly used reagents with their cas registry numbers 7664-41-7 and 106-89-8 in this article. soln. contg. 59.14% II, heated at 75-95.degree. to thicken the mixt., and dild. with 195 kg water to prep. a polycondensate. .
