An autoclave reactor having a volume content of 50 liters which was sufficiently substituted with nitrogen was charged in order with 20 liters of n-hexane, 12.5 mmol of triethylaluminum and 82 mmol of 1,9-decadiene and stirred for 5 minutes. Then, 3.3 g of the pre-activated metallocene supported catalyst prepared above was added, and a temperature of the reactor was elevated to 60° C. Propylene was fed so that a pressure of the reactor became a fixed pressure of 1 MPaG and reacted for 2 hours. After finishing the reaction time, 500 ml of methanol was added to terminate the reaction, and unreacted propylene was removed, followed by filtering the hexane slurry, whereby a powder of a propylene/1,9-decadiene copolymer was obtained. The powder thus obtained was dried at 60° C. for 8 hours to obtain 7 kg of the propylene/1,9-decadiene copolymer. Results of analysis thereof showed that a content of 1,9-decadiene in the copolymer was 0.03% by weight. The resulting propylene/1,9-decadiene copolymer had an MFR of 2.8 g/10 minutes. The same copolymer was produced three times to obtain total 21 kg of the propylene/1,9-decadiene copolymer, and a blend thereof was used to produce the following foamed matters.
