FIELD: chemistry.
SUBSTANCE: invention relates to a copolymer of propylene. Copolymer of propylene (R-PP) contains ethylene in the range of 2.0-11.0 mol%. MFR flow rate2 (230°C), measured according to ISO 1133, is 25.0-100.0 g/10 minutes. Relative content of the I(E) molar fraction of the propylene/ethylene/propylene sequences (PEP) in the sample is 45.0-70.0%. Content of I(E) is determined using equation (I). Process for the preparation of a propylene copolymer is also described, a product obtained by injection molding, and a thin-walled package. .
EFFECT: technical result is the preparation of a copolymer of propylene having high impact and optical properties.
