An environmentally-friendly solid catalyst component for olefin polymerization exhibits high hydrogen activity and high polymerization activity, can produce a polymer that exhibits a high MFR and high stereoregularity in high yield using a small amount of hydrogen, and exhibits high copolymerization activity and excellent copolymerization properties (e.g., block ratio). The solid catalyst component for olefin polymerization is produced by bringing (a) a magnesium compound, (b) an internal electron donor, and (c) a tetravalent-element halogen compound into contact with each other in an inert organic solvent, the internal electron donor (b) being represented by R12C(COOCH3)2 (wherein R1 is selected from a branched alkyl group having 3 to 20 carbon atoms, a halogen atom, a linear or branched halogen-substituted alkyl group having 2 to 20 carbon atoms, a linear alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, a vinyl group, and an allyl group).
一种用于烯烃聚合的环境友好型固体催化剂组分具有高氢活性和高聚合活 性,可使用少量氢气生产出高 MFR 和高立体规整度的聚合物,并具有高共聚活 性和优异的共聚特性(如嵌段比)。用于烯烃聚合的固体催化剂组分是通过在惰性有机溶剂中使(a)镁化合物、(b)内部电子供体和(c)四价元素卤素化合物相互接触而制得的、内部电子供体 (b) 由 R12C(COOCH3)2 表示(其中 R1 选自具有 3 至 20 个碳原子的支链烷基、卤原子、具有 2 至 20 个碳原子的直链或支链卤代烷基、具有 1 至 20 个碳原子的直链烷基、具有 3 至 20 个碳原子的环烷基、乙烯基和烯丙基)。
