Abstract
A homopolypropylene has i) a molecular weight distribution of less than 2.4; ii) a melt index (measured at 230° C. under a load of 2.16 kg in accordance with ASTM D1238) of 5 to 3000 g/10 min; iii) a remaining stress ratio of 0.5% or less; and iv) a complex viscosity of 5 to 600 Pa·s at an angular frequency of 1 rad/s and a complex viscosity of 5 to 300 Pa·s at an angular frequency of 100 rad/s. A method for preparing the homopolyproylene is also provided. A molded article and a non-woven fabric are also provided.
