✦ Synopsis

Ring opening metathesis polymerization (ROMP) of dicyclopentadiene (DCPD) catalyzed by titanium tetrachloride adduct complexes such as TiCl 4 ⅐ 2L [L ϭ pyridine (1), 2-methylpyridine (2), 2,4,6-trimethylpyridine (3), 3-aminopyridine (4), 2-hyroxypyridine (5)] and CH 3 Li as cocatalyst was reported. The polymer was characterized by IR and 1 H-NMR methods. Five influencing factors were also discussed. The catalyst systems TiCl 4 ⅐ 2L/CH 3 Li (L ϭ 2-methylpyridine, 2,4,6-trimethylpyridine) appeared to be very active for the ROMP of DCPD.
