摘要： The present disclosure relates to olefin polymerization catalysts, and discloses a catalyst component for olefin polymerization or copolymerization and a preparation method therefor, and a catalyst and an application thereof. The catalyst component for olefin polymerization or copolymerization in the present disclosure comprises titanium element, magnesium element, an electron donor, an organic silicon polymer, and an inorganic oxide support, wherein the molecular composition of the organic silicon polymer is [R x SiO (4-x)/2 ] m , wherein R is selected from alkyl, aryl, vinyl or oxygen, x is 0 or more and 2 or less, and the value of m makes the number-average molecular weight of the organic silicon polymer be 1×10 3 -1×10 6 g/mol. The catalyst has the characteristics of high activity, good hydrogen-regulating copolymerization performance, high bulk density of resulting polymer powder, and a low content of fine powder in the polymer powder when applied to olefin polymerization, particularly to ethylene and α-olefin polymerization.
