FIELD: chemistry.
SUBSTANCE: present invention is related to thermoplastic polyolefin compositions and made of articles. Composition of the random propylene copolymer contains (A) 60-85 wt% copolymer including propylene and from 0.1 to 2 wt% of links formed from ethylene, and (B) 15-40 wt% copolymer containing propylene and from 7 to 17 wt% of links formed from ethylene. Note here that the said composition has full content of ethylene, varying from 3 to 4.5 wt%, and melt flow rate value (TCS), equal to 10 to 120 g/10 min, the said composition is processed by splitting in order to increase THERMAL CONTROL SYSTEM, When the value of TCS ranges from 50 to 120 g/10 min but not subjected to any splitting in order to increase value TCS, when the value of TCS ranges from 10 to 60 g/10 min. Film manufactured with casting, which is made from the said composition, is also described.
EFFECT: technical result is producing of compositions suitable for production of molded articles, as well as with high hardness, impact strength and transparency.
