Polypropylene Compositions and Their Uses |
| abstract |
The present invention relates to polypropylene compositions of (A) polypropylene and (B) propylene-1-butene random copolymers in specific weight ratios. Propylene-1-butene random copolymer (1) The copolymer contains 50 to 95 mol% of propylene structural units and 50 to 5 mol% of 1-butene structural units, and (2) measured in decahydronaphthalene at 135 ° C. Intrinsic viscosity is in the range of 0.1-12 dl / g, (3) Molecular weight distribution (Mw / Mn) measured by GPC is 3 or less, and (4) Parameter B value which shows the randomness of copolymerized monomer sequence is 1.0- It is characterized in that 1.5. The present invention also relates to a polypropylene composite film in which a polypropylene composition layer (II) is laminated on at least one surface of the crystalline polypropylene layer (I). The polypropylene composition not only has excellent heat resistance and low temperature heat sealing property, but also excellent flexibility and impact resistance. Polypropylene composite films not only have excellent heat sealability, especially low temperature heat sealability, but also excellent transparency, scratch resistance and block resistance. |
