Abstract:
1. A polyolefin which comprises recurring units derived from propylene in amounts of 50 to 99.5% by mol and recurring units derived from at least one olefin selected from α-olefins of 2 to 20 carbon atoms other than propylene in amounts of 50 to 0.5% by mol, and has the following properties: (i) the proportion of 2,1-insertion is not more than 0.03% and the proportion of 1,3-insertion is not more than 0.1%. (ii) the molecular weight distribution (Mw/Mn) as determined by gel permeation chromatography is in the range of 1.7 to 2.5, and (iii) the quantity of a decane-soluble component is not more than 2% by weight.
