摘要:
A process for producing an .alpha.-olefin polymer which comprises polymerizing an .alpha.-olefin in the presence of a catalyst system comprising(A) a solid catalyst component obtained by steps of(i) reducing titanium tetrachloride with an organoaluminum compound represented by the general formula R.sup.1.sub.n AlY.sub.3-n, wherein R.sup.1 represents a C.sub.1 -C.sub.18 hydrocarbon group, Y represents a halogen, and n represents a number satisfying 1
