Claim 8:
9. The catalyst component according to claim 1, wherein the magnesium source is prepared by a method comprising the following steps:
(1) preparing a mixture, wherein the mixture comprises elemental sulfur, a magnesium halide represented by a general formula MgX1Y, a compound represented by a general formula R1OH, an optional inert liquid medium, and an optional surfactant; and
(2) subjecting the mixture obtained in step (1) to a contact reaction with an ethylene oxide compound;
wherein in the general formula MgX1Y, X1 is a halogen; and Y is selected from the group consisting of halogen, substituted or unsubstituted C1-C10 linear alkyl, substituted or unsubstituted C3-C10 branched alkyl, substituted or unsubstituted C3-C10 cycloalkyl, substituted or unsubstituted C6-C20 aryl, substituted or unsubstituted C1-C10 alkoxy, substituted or unsubstituted C6-C20 aryloxy, substituted or unsubstituted C7-C20 aralkyl, and substituted or unsubstituted C7-C20 alkaryl;
in the general formula R1OH R1 is selected from the group consisting of substituted or unsubstituted C1-C10 linear alkyl, substituted or unsubstituted C3-C10 branched alkyl, substituted or unsubstituted C3-C10 cycloalkyl, substituted or unsubstituted C6-C20 aryl, substituted or unsubstituted C7-C20 aralkyl, and substituted or unsubstituted C7-C20 alkaryl; and
the ethylene oxide compound is of Formula V:, wherein in Formula V, R25 and R26 are each independently selected from the group consisting of hydrogen, substituted or unsubstituted C1-C10 linear alkyl, substituted or unsubstituted C3-C10 branched alkyl, substituted or unsubstituted C3-C10 cycloalkyl, substituted or unsubstituted C6-C20 aryl, substituted or unsubstituted C7-C20 aralkyl, and substituted or unsubstituted C7-C20 alkaryl.
