摘要：
There is described an α-olefin polymerizing catalyst consisting of
(A) a solid catalyst component containing magnesium, titanium, halogen and an electron donative compound as essential components,
(B) an organoaluminum compound, and
(C) an electron donative compound component,
for use in the production of an α-olefin polymer which is an α-olefin polymer obtained by polymerizing an α-olefin having 3 or more carbon atoms and satisfying the following conditions:
the intrinsic viscosity [η] of said polymer is not lower than 0.5 and not higher than 10, and
20°C xylene-soluble fraction (CXS) content (% by weight) and 105°C xylene-insoluble fraction (XIS) content (% by weight) of said polymer satisfy the following condition: XIS ≤ 70.00 - 3.64CXS provided that CXS is not smaller than 0 and not greater than 15.
