Problems solved by technology

[0005] However, the catalyst disclosed above still has some unsatisfactory defects in the practical application of olefin polymerization. The compound can be used as an electron donor to obtain a catalyst with excellent comprehensive performance. When used in the polymerization of propylene, a satisfactory polymerization yield can be obtained, and the stereospecificity of the polymer is high. At the same time, the catalyst has good hydrogenation sensitivity. It is very beneficial to the development of different grades of resin

Abstract

The invention provides catalyst components used for CH2=CH olefin polymerization reaction and a catalyst, wherein R is alkyl or aryl of hydrogen or C1-C6. The catalyst components comprise magnesium, titanium, halogen and electron donors. The electron donors are at least one of amine ester compounds presented as the following general formula (I), wherein, R1 is the aryl or alkaryl of C6-C20; R2 and R3 can be the same or different, which are the alkyl of the hydrogen or a straight chain or a branched chain of the C1-6, and the aryl, aralkyl, ester group or acyl of the C6-C20, but R2 and R3 can not be the hydrogen at the same time. A is a divalent linking group whose chain length is 1 to 15 carbon atoms. Hydrogen atoms on the divalent linking group can be substituted by the alkyl, amino-alkane or the acyl. When the catalyst is used in propylene polymerization, a satisfied polymerization yield can be obtained, and the polymer is in higher stereospecificity and is helpful to develop the different grades of the polymers.
