CLASS: ICM: C08F010-00. ICS: C08F004-64. APPLICATION: JP 85-93546 2 May 1985. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 67 In prepn. of polyolefins by prepolymg. olefins in the presence of Ti compds. and org.Some commonly used reagents like 97-93-8 and 5666-17-1 are used in this experiment. Al compds. to form 1-100 g/g-Ti compd. polymers followed by polymn. of the catalyst-contg. polymers, organometallic intramol. complexes are used as catalyst components in prepolymn. and/or polymn. to widen the mol. wt. distribution and improve fluidity. C3H6 was prepolymd. in presence of TiCl3 and Et2AlCl at 50° for 1 h forming a 10 g-polymer/g-catalyst compd. and further stirred at 50° for 10 min with Et2N(CH2)3Al(iso-Bu)2 (I) and Et anisate (II) to give a polymer-catalyst slurry. Liq. C3H6 was autoclaved with H, Et2AlCl, and the slurry at 65° for 3 h forming polypropylene with melt index 8.0 g/10 min, wt.-av. mol. wt./no.-av. mol. wt. 24.2, spiral flow 55 cm, and flexural modulus 16,000 kg/cm2, vs. 10.0 , 8.1, 45, and 15,000, resp., for polypropylene prepd. without I and II. .
