Abstract: The β-cryst. form of TiC14 was combined with Et2A1C1 and an org. ether to give a brown solid having surface area >50 m2/g and pore vol. >0.10 cm3/g. The brown solid led to improved polmn. rates and yields in the polymn. of α-olefin (esp. propen). Thus, 74.8ml Et2A1C1 in hexane was reacted with 12.5ml TiC14 and hoxane. Hexane and 21.3ml isopentyl ether were reacted for 2hr at 65oC after 70.8ml TiC14 in hexane (20.3% soln.) were added. 3rd decantation gave 0.295g brown solid.
