| titleOfInvention | Crystalline polypropylene, process for preparing the same, polypropylene composition, and thermoformed article |
| abstract | The present invention presents crystalline polypropylenes that contain components insoluble in 64°C decane that satisfy the following characteristics (1) to (5) and are excellent in hardness and rigidity, high in melt tension, and excellent in molding properties, process for preparing such crystalline polypropylenes, and polypropylene compositions and thermoformed products that contain such crystalline polypropylenes. (1) The intrinsic viscosity (.eta.) (in 135°C decalin) is 0.5 to 10dl/g. (2) The molecular weight distribution (Mz/Mw) as determined by gel permeation chromatography (GPC; solvent: o-chlorobenzene, measurement temperature: 140°C) is 5 or more. (3) The pentad isotacticity (mmmm percentage), which is a stereoregularity index determined by the measurement of the 13C-NMR spectrum, is 98% or more. (4) The D value, determined using formula (1) below from the loss tangents, tan.deltaØ05 and tan.delta.10 measured at the frequencies, 0.05rad/sec and 10rad/sec respectively by a melt viscoelasticity measuring device under a temperature of 230°C and constant strain, and said loss tangent measurement frequencies, is 4.0 or more. (5) The molecular weight distribution (Mw/Mn) as determined by gel permeation chromatography (GPC; solvent: o-dichlorobenzene, measurement temperature: 140°C) is 6.0 to 20. It is preferable for the number-average molecular weight Mn of the components insoluble in 64°C decane to be 25000 or more. |
