PROPYLENE POLYMER-BASED COMPOSITIONS Russian patent published in 2014 - IPC C08L23/14 C08F297/08 

Abstract RU 2528384 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a propylene composition for producing moulded articles. The propylene composition includes (in wt %) 60-90% of a crystalline propylene copolymer containing 3.5-10.0% of links formed by ethylene, and having a melting point Tm (measured by DSC method on a reactor polymer) in the range of 146°C to 160°C, and 10-40% of propylene copolymer containing 15-30% of links formed by ethylene.

EFFECT: improved impact strength, softness and optical properties of the propylene composition.
