Effect of ligands and solvents on ethylene polymerization and oligomerization catalyzed by the Ti(OR)nCl4-n-AlEtCl2 system

Effect of ligands and solvents on ethylene polymerization and oligomerization catalyzed by the Ti(OR)nCl4-n-AlEtCl2 system. Xu, Yun; Liao, Shihtsien; Liu, Rongzhi; Wang, Guoxi; Guo, Hefu (Dalian Inst. Chem. Phys., Acad. Sin., Dalian, Peop. Rep. China). Cuihua Xuebao, 5(2), 168-73 (Chinese) 1984. CODEN: THHPD3. ISSN: 0253-9837. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) In the polymn. catalyzed by TiCl4, (BuO)4Ti [5593-70-4], or (BuO)2TiCl2 [1790-25-6] and AlEtCl2 [563-43-9] (cocatalyst), ligands mainly affected the redn. rate of Ti. At the same Ti valence state, ligands did not markedly change the ratio between the chain propagation rate and the chain transfer rate. The valence state of Ti was a major factor in influencing the ratio. A linear relation was obsd. between the catalyst activity and the Taft induction consts. of various chloroalkane solvents.

Olefin copolymers

Olefin copolymers. (Toa Nenryo Kogyo K. K., Japan). Jpn. Kokai Tokkyo Koho JP 59043003 A2 9 Mar 1984 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F004-64; C08F210-02. APPLICATION: JP 82-152767 3 Sep 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) A copolymer is prepd. by treating a complex formed from an unsatd. ester and a Lewis acid with an olefin in the presence of a TiCl3 catalyst component and an org. Al compd. Thus, 800 mL H and 600 mL liq. propylene were introduced into a mixt. of 6.25 mmol Me undecenoate, 6.9 mmol EtAlCl2 [563-43-9], 83 mg of a catalyst made from TiCl4 and Et2AlCl(I), and 7.8 mmol I. The mixt. was heated to 70° and kept at that temp. for 1 h to give 85.6 g copolymer [91422-05-8] having bulk d. 0.52 g/cm3, melt index 2.3, ester content 0.11 mol%, and heptane-insol. portion 98.4%. The catalyst efficiency was 1030 g/g catalyst-h.
