    • Process for modifying the relative ratios of the components of a liquid starting mixture of specific diastereoisomers, containing at least two asymmetric carbon atoms comprising contacting said liquid mixture with a Lewis acid compound capable of co-ordinating said specific diastereoisomers and subjecting the resulting mixture to conditions such that a reaction product, having a molar ratio between its diastereoisomeric components different from the corresponding molar ratio in the said liquid starting mixture, becomes separated from the said liquid mixture, said process being carried out using an amount of said Lewis acid not enough to co-ordinate the total amount of the diastereoisomeric components of the liquid starting mixture. This method shows an excellent balance of efficiency and easiness of procedure that cannot be reached with the physical methods of diastereoisomers separation known in the art.
    • 用于改变含有至少两个不对称碳原子的特定非对映异构体的液体起始混合物的组分的相对比例的方法,包括使所述液体混合物与能够协调所述特定非对映异构体的路易斯酸化合物接触,并将所得混合物进行条件 使得具有与所述液体起始混合物中的相应摩尔比不同的非对映异构体的摩尔比的反应产物与所述液体混合物分离,所述方法使用一定量的所述路易斯酸进行,所述量不足以 统计液体起始混合物的非对映异构体组分的总量。 该方法显示出与本领域已知的非对映异构体分离的物理方法无法达到的效率和程序容易性的极好的平衡。

    • The present invention relates to catalyst components for the polymerization of olefins comprising Mg, Ti, halogen and at least two electron donor compounds, said catalyst component being characterized by the fact that at least one of the electron donor compounds, present in an amount from 20 to 50% by mol with respect to the total amount of donors, is selected from esters of succinic acids which are not extractable, for more than 25% by mol and at least another electron donor compound which is extractable, for more than 35%. The said catalyst component-are capable to give polymers with high xylene insolubility, high stereoblock content and broad MWD suitable for making the polymers usable in the BOPP sector.
