The present invention relates to a process for manufacturing atacticnethylene/α-olefin copolymers, atactic ethylene/α-olefin copolymers, andncompositions thereof and the process for manufacturing such compositions. n The ethylene/propylene copolymers of the present invention comprisenethylene and propylene whose structural molar ratio (ethylene/propylene) isn1/99 to 20/80 and out of the spectra in the zone (19 to 23 ppm) obtained byn 13 CNMR measurement, the areas of the signals appearing in the first zonen(21.1 to 21.9 ppm), second zone (20.3 to 21.0 ppm) and third zone (19.5 to 20.3nppm) have a specific proportion. |
