In a stainless steel autoclave (inner volume: 5 l) was performed polymerization of propylene using 1.06 g of the above-described vinylcyclohexane polymerization catalyst, 0.75 g of triethyl aluminium, 0.237 g of methyl p-toluylate and 1,500 ml of n-heptane under the conditions of a pressure of 6 kg/cm2 gauge and a temperature of 70° C. and a hydrogen concentration of 1.5% by volume for 40 minute. After completion of the polymerization, 50 ml of n-butanol was added to stop the polymerization and the resulting polymer slurry was taken out followed by the separation of polymer powder and solvent by filtration. After washing the polymer powder with 500 ml of 1N hydrochloric acid, further washing was performed with methanol until the washings became neutral.
