Title:
【発明の名称】塩化マグネシウム―アルコール付加物その製造法およびそれから得られた触媒成分
Document Type and Number:
Japanese Patent JP2000512309
Kind Code:
A
Abstract:
The present invention relates to MgCl2.mROH.nH2O adducts, where R is a C1-C10 alkyl, 2=m=4.2, 0=n=0.7, characterized by an X-ray diffraction spectrum in which, in the range of 2 theta diffraction angles between 5 DEG and 15 DEG , the three main diffraction lines are present at diffraction angles 2 theta of 8.8+/-0.2 DEG , 9.4+/-0.2 DEG and 9.8+/-0.2 DEG , the most intense diffraction lines being the one at 2 theta =8.8+/-0.2 DEG , the intensity of the other two diffraction lines being at least 0.2 times the intensity of the most intense diffraction line. Catalyst components obtained from the adducts of the present invention are capable to give catalysts for the polymerization of olefins characterized by enhanced activity and stereospecificity with respect to the catalysts prepared from the adducts of the prior art.
