Notes:
1-Vinylnaphthalene, 2-vinylnaphthalene, 4-vinylbiphenyl, and styrene were polymerized with Et3Al-TiCl4, Et2AlCl-TiCl3, and Et3Al-TiCl3 catalyst systems. The latter catalyst system gave polymers in 75-95% conversion which were at least 90% isotactic. Extraction with 2-butanone (MEK) separated the atactic from the isotactic fractions. The polymers were characterized by infrared and nuclear magnetic resonance spectroscopy.
