Polypropylene/propylene-ethylene copolymer composition and process for producing the same |
| abstract |
An object of this invention is to provide a polypropylene/propylene-ethylene copolymer composition having an excellent balance among rigidity, toughness, impact resistance, etc. This invention provides a polypropylene/propylene-ethylene copolymer composition having a melt flow rate of from 1 to 80 g/10 min obtained by producing a specific propylene polymer in an amount of from 60 to 95% by weight based on the total amount of the composition to be finally obtained and subsequently producing in a second stage (polymerization step (II)) a specific propylene-ethylene copolymer in an amount of from 5 to 40% by weight based on the total amount of the composition to be finally obtained. A process for producing the composition is also provided. |
