Embodiment 1
[0071] In a 1000L SUS pressure polymerization vessel cleaned with nitrogen, 700L of n-hexane purified by degassing and dehydration was charged, and then a dry mixture containing ethylene, propylene and hydrogen was added to it at a volume ratio of 6:4:1. gas, and stirred at room temperature for 60 minutes to dissolve. Next, 5 mol of ethyl aluminum sesquichloride (Al 2 Et 3 Cl 3 ) and 0.5mol of VOCl 3 The resulting solution was charged, and the contents in the polymerization vessel were allowed to react with each other at 35° C. for 1 hour while maintaining the internal pressure at 0.5 MPa with the above-mentioned mixed gas. Afterwards, the catalyst was deactivated with isopropanol to stop the polymerization.
[0072] The copolymer solution thus obtained was distilled under reduced pressure, and 400 L of the solvent was removed therefrom to obtain a concentrated solution. The resulting concentrated solution was transferred to a kneader, heated and distilled under reduced p...
Embodiment 2
[0074]Except that the volume ratio of ethylene, propylene and hydrogen was changed to 6:4:2, the same procedure as specified in Production Example 1 was followed, whereby 39 kg of an ethylene-propylene copolymer (hereinafter sometimes referred to as an olefin-based elastomer) was obtained. (2)). As a result of H-NMR analysis, it was confirmed that the molar ratio of ethylene to propylene in the obtained product was 81:19. Also, as a result of GPC measurement, it was confirmed that the obtained product had a weight average molecular weight of 100,500 and a molecular weight distribution of 2.5. Furthermore, it was confirmed that the density of the obtained product was 0.860 g / cc. In addition, the heat of fusion of the obtained product was confirmed to be 11 J / g as measured by the DSC method at a temperature of 0 to 200°C.
Embodiment 3
[0076] A 1000 L SUS pressure polymerization vessel was purged with a mixed gas of ethylene and propylene at a partial pressure ratio of 85:15, and then charged with 750 L of degassed and dried toluene. Then, a toluene solution of methylaluminoxane produced by Witco Co., Ltd. containing 100 mol of Al was charged into the reaction system, and the resulting mixture was stirred at 700° C. for 30 minutes. After that, 0.1 mol of metallocene catalyst (dimethylsilylene biscyclopentadienyl zirconium dichloride) was added to the polymerization vessel, and the contents in the polymerization vessel were polymerized for 2 hours while mixing with ethylene and propylene. The pressure of gas was applied to the inside of the polymerization vessel to 0.7 MPa. Afterwards, the polymerization was stopped by adding isopropanol.
[0077] The copolymer solution thus obtained was distilled under reduced pressure to remove 400 L of solvent therein to obtain a concentrated solution. The resulting conc...
