Highly rigid propylenic resin and blow molded article made therefrom |
| 摘要 |
There are provided a highly rigid propylenic resin which has a melt index MI in the range of 0.1 to 1.2 g/10 minutes as determined at 230 DEG C. under 2.160 kg load and also satisfies a relationship between the MI and the elongational viscosity [Y(Pa.s)], said relationship being represented by the expression2.0x105xMI-0.68</=Y</=8.0x105xMI-0.68;and a blow molded article made from the above resin. The propylenic resin has favorable resistance to draw down and can produce a large-sized and lightweight blow molded article excellent in rigidity, dimensional stability and heat resistance.
