| titleOfInvention | Heterophasic polypropylene composition with improved balance of properties |
| abstract | The present invention is directed to a heterophasic polypropylene composition having an improved balance of desirable properties, i.e. high stiffness, high toughness, and high transparency. The heterophasic polypropylene composition of the present invention comprises 60.0 to 95.0 wt% of a crystalline propylene homopolymer with a melting temperature Tm1 measured by differential scanning calorimetry of higher than 155 °C, 5.0 to 20.0 wt% of an elastomeric ethylene-propylene rubber, and at least one polymeric nucleating agent, wherein the crystalline propylene homopolymer (H-PP) and the elastomeric ethylene-propylene rubber (EPR) have been produced in the presence of a single-site catalyst, wherein the heterophasic polypropylene composition is characterized by a soluble fraction determined in 1,2,4-trichlorobenzene at 40 °C in the range of 5.0 to 20.0 wt%, and wherein the soluble fraction has an ethylene content in the range of 12.0 to 40.0 wt%. The present invention is further directed to a process for the preparation of the heterophasic polypropylene composition comprising polymerizing propylene in at least three polymerization steps in the presence of a single-site catalyst, wherein the at least one polymeric nucleating agent is introduced either as a master batch by a compounding step or via a prepolymerization step prior to the first polymerization step. The present invention is further directed to an article obtained by extrusion of the heterophasic polypropylene composition, and to a packaging article comprising the extruded article.Finally, the present invention is directed to the use of the heterophasic polypropylene composition for the production of extruded articles such as films or sheets. |
