PROPYLENE POLYMER, AND RESIN COMPOSITION AND MOLDED PRODUCT THEREOF |
| 摘要 |
<p>The propylene polymer of the present invention satisfies (1) a 25 DEG C hexane soluble content (H25) of 0-80 wt%; and (2) either no melting temperature (Tm) measurable by differential scanning calorimetry (DSC), or a melting temperature (Tm) satisfying, if measurable by DSC, the following relationship: DELTA H>/=3 x (Tm - 120) wherein DELTA H is a melting endotherm (J/g). The propylene homopolymer of the present invention satisfies (1) a meso pentad fraction (mmmm) of 30-60 mol%; (2) a racemic pentad fraction (rrrr) satisfying the following relationship: Ärrrr/(1-mmmm)Ü </= 0.1; (3) a fraction (W25) eluted at a temperatures up to 25 DEG C by temperature-programmed chromatography, of from 20-100 wt%; and, (4) a pentad fraction (rmrm) of more than 2.5 mol%. The propylene copolymer of the present invention satisfies (1) a stereoregularity index (P) of 55-90 mol% as determined by <13>C-NMR measurement; and (2) a fraction (W25) eluted at a temperatures up to 25 DEG C by temperature-programmed chromatography, of from 20-100 wt%.</p> |
