| titleOfInvention | Propylene-ethylene block copolymer and molded body using the same |
| abstract | The present invention provides a novel propylene-ethylene block copolymer which is suppressed in stickiness and bleed-out and has excellent transparency, and a molded body using the same. A crystalline propylene-ethylene random copolymer component (A) is polymerized in a first step, and a low crystalline or amorphous propylene-ethylene random copolymer component (B) is sequentially polymerized in a second step. Provided by a propylene-ethylene block copolymer or the like characterized by satisfying the following conditions (i) to (v). (I) The ethylene content [E (A)] of the copolymer component (A) is 0.3 to 10% by mass, (ii) the ratio of the copolymer component (B) to the total amount of the copolymer [W (B)] is 10 to 70% by mass, (iii) the ethylene content [E (B)] of the copolymer component (B) is 35 to 75% by mass, and (iv) the copolymer component. The -15 ° C soluble content [S (A)] by TREF of (A) is 0.8% by mass or less, (v) MFR [MFR (A)] of copolymer component (A), Ratio of MFR [MFR (B)] of polymer component (B): MFR (A) / MFR (B) is 0.25 or more and 4.0 or less. [Selection figure] None |
