Fibers and fibrous moldings made by using the same

A fiber formed from a polypropylene serving as at least one raw material, wherein the polypropylene has

• (a) an isotactic pentad fraction (mmmm) of 0.950-0.995,
• (b) a syndiotactic pentad fraction (rrrr) of 0-0.004,
• (c) different bonds due to 2,1-insertion reaction and 1,3-insertion reaction in an amount of 0-0.3 mol %, and
• (d) absence of terminal double bonds, each of which was confirmed with NMR spectrometry, and has
• (e) a weight average molecular weight (Mw) of 50,000-1,000,000 and
• (f) a ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight of 1.5 to 3.8,
• said polypropylene being manufactured through the use of a chiral transition metal compound represented by the following formula
• wherein each of C5H4−m and C5H4−nR2n represents a substituted cyclopentadienyl group;
• each of m and n represents an integer of 1-3;
• each of R1 and R2, which may be identical to or different from each other, represents a C1-20 hydrocarbon group;
• a silicon-containing hydrocarbon group, or a hydrocarbon group bonding to two carbon atoms contained in the cyclopentadienyl ring thereby to form one or more hydrocarbon rings which may have ring hydrogen further substituted with a hydrocarbon group;
• Q represents a group that can be cross-linked with C5H4−m, R1m and C5H4−nR2n, non-substituted silylene, or hydrocarbon-substituted silylene group;
• M represents a transition metal selected from a group of titanium, zirconium, and hafnium;
• and each of X and Y, which may be identical to or different from each other, represents hydrogen, a halogen, or a hydrocarbon group, as catalyst in the presence of hydrogen.
