Claims21
An alkoxymagnesium particle, comprising a reaction product of following components:
- 1) magnesium powder;
- 2) a mixed alcohol;
- 3) a halogenating agent;
- and 4) a titanate compound.
An alkoxymagnesium particle, comprising a titanate compound in the particle.
A Ziegler-Natta catalyst component, comprising a reaction product of the following components:
- A) an alkoxymagnesium particle comprising a titanate compound of Formula I:
- (R1O)aTi(OR2)b(OR3)cXd Formula I;
- B) a titanium-containing halide;
- and
- C) an electron donor compound, which is preferably at least one selected from a group consisting of a carboxylate compound, a 2,3-di-non-linear alkyl-2-cyano disuccinate compound, and an aliphatic ether compound;
- wherein, preferably, an amount of the electron donor compound used is 0.005-10 mol relative to an amount of magnesium in 1 mol of a dialkoxymagnesium compound;
- and/or an amount of the titanium-containing halide is 0.5-100 mol, more preferably 1-50 mol.
