Procedure

Tetracyclododecene (20 g) containing 35,000 ppm of the compound having a molecular weight of 188 obtained in Example 2, norbornene (2.5 g), dicyclopentadiene (2.5 g) and toluene (200 ml) were introduced into an entirely dried autoclave of 500 ml. Triethylaluminum (3 mmol) was added to the above mixture, and further, tetrachlorotitanium (0.7 mmol) and triethylamine (7 mmol) were added to carry out a ring opening polymerization at 30° C. for 6 hours.
