Procedure
The resulting polymer had a propylene unit content of 61.3% by mol, an ethylene unit content of 10.3% by mol, a 1-butene unit content of 28.4% by mol, an intrinsic viscosity [η] of 2.67 dl/g and a glass transition temperature Tg of −27.7° C. In the DSC measurement, a melting peak was not observed, and the molecular weight distribution (Mw/Mn), as measured by GPC, was 2.0. According to the 13C-NMR spectrum as measured in a 1,2,4-trichlorobenzene solution using tetramethylsilane as a reference material, the sum total of absorptions of methyl groups of propylene units (propylene methyl groups) observed at about 20.0 to 21.0 ppm was 0.8 time the absorption intensities assigned to propylene methyl groups observed at about 19.0 to 22.0 ppm.
