CONTAINERS FROM PROPYLENE-BASED TERPOLYMERS Russian patent published in 2019 - IPC B65D1/00 

FIELD: chemistry.

SUBSTANCE: container consisting of propylene, ethylene, 1-butene terpolymer, where terpolymer: i) content of ethylene units ranges from 0.5 wt. % to 1.8 wt. %; ii) content of 1-butene units ranges from 1.5 wt. % to 2.5 wt. %; iii) ratio wt. % C2/C4 ranges from 0.40 to 0.80, where the weight ratio of ethylene units and wt. % C4 is equal to the weight ratio of 1-butene units; iv) melt flow rate (MFR), measured in accordance with ISO 1133, 230°, 2.16 kg, ranges from 30 to 80 g/10 min; v) fraction soluble in xylene at 25 °C is less than 5.0 wt. %; (vi) melting point higher than 140 °C.

EFFECT: disclosed are containers from propylene-based terpolymers.
