    摘要： The invention provides a metallocene catalyst for use in preparing syndiotactic polyolefins. The catalyst comprises a bridged metallocene in which one of the cyclopentadienyl rings is substituted in a substantially different manner from the other ring. It was discovered that this type of catalyst is highly syndiospecific, and it also produces a polymer with a novel microstructure. The invention further includes the use of one or more of the catalysts in a polymerization process. The catalyst is generally described by the formulaR"(CpR.sub.n)(CpR'.sub.m)MeQ.sub.kwherein each Cp is a cyclopentadienyl or substituted cyclopentadienyl ring; each R.sub.n and R'.sub.m is the same or different and is a hydrocarbyl radicals having 1-20 carbon atoms; R" is a structural bridge between the two Cp rings imparting stereoigidity to the catalyst; Me is a group 4b, 5b, or 6b metal from the Periodic Table of Elements; each Q is a hydrocarbyl radical having 1-20 carbon atoms or is a halogen; 0.ltoreq.k.ltoreq.3; 0.ltoreq.n.ltoreq.4; 1.ltoreq.m.ltoreq.4; and wherein R'.sub.m is selected such that (CpR'.sub.m) is a sterically different ring than (CpR.sub.n).

    摘要： The present invention provides a process for producing an α-olefin polymer comprising polymerizing or copolymerizing (a) C3 or higher α-olefin(s) in the presence of an olefin polymerization catalyst comprising solid titanium catalyst component (I) containing titanium, magnesium, halogen, and a compound with a specific structure having two or more ether linkages and organometallic catalyst component (II) with high catalytic activity. In this process, particularly even in (co)polymerizing (a) higher olefin(s), demineralization is unnecessary. A 4-methyl-1-pentene-based polymer obtained by polymerization using the catalyst of the present invention is excellent in tacticity, transparency, heat resistance, and releasability, and the polymer is particularly suitable for a release film.

    摘要： A process for the manufacture of a modified titanium component for catalysts of the Ziegler/Natta type by milling a mixture of a titanium compound of the formula TiCl.sub.3 .13AlCl.sub.3 and an organic electron donor containing phosphorus and/or nitrogen atoms. The characterizing feature is that the mixture is first milled wet in a liquid inert hydrocarbon medium under specific conditions, then separated from the hydrocarbon medium and finally milled dry under specific conditions. Such modified titanium components give catalysts which provide particularly well reproducible results in the polymerization of .alpha.-olefins.
