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.degree. C. under 2.160 kg load and also satisfies a relationship between the MI and the elongational viscosity �Y(Pa.multidot.s)!, said relationship being represented by the expression 2.0.times.10.sup.5 .times.MI.sup.-0.68 .ltoreq.Y.ltoreq.8.0.times.10.sup.5 .times.MI.sup.-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.
