POLYPROPYLENE COMPOSITION WITH LOW SHRINKAGE IN WIDE RANGE OF APPLICATION TEMPERATURES Russian patent published in 2020 - IPC C08L23/16 C08F210/16 C08F2/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a polypropylene composition having a melt flow index MFI₂ (230 °C), measured according to ISO 1133 in amount of 5–50 g/10 min, to a composition containing said polypropylene composition and one or more additives in amount of up to 4 wt. % with respect to total weight of composition, method of producing polypropylene composition and article containing polypropylene composition, as well as to use of polypropylene composition for production of films, extruded, produced with blowing or injection-moulded articles.

EFFECT: technical result is obtaining a propylene composition, having a good balance between shrinkage and mechanical properties, low temperature transition from brittleness to plasticity.
