摘要： A catalyst component for olefin polymerization which comprises an intimate mixture of: Component (A1) which is a solid component for Ziegler catalysts comprising titanium, magnesium and a halogen as essential components in a particulate form; and Component (A2) which is a compound selected from the group consisting of inorganic oxides, inorganic carbonates, inorganic sulfates and physical or chemical mixtures thereof in a particulate form; wherein Component (A2) is employed in a weight ratio to Component (A1) from 0.001 to 0.5 and has an average particle diameter smaller than that of Component (A1). The catalyst component may be of a structure such that the particulate inorganic material, Component (A2), adhere to or cover particles of a solid component of a Ziegler catalyst, whereby fluidity of the Ziegler catalyst component is improved.
摘要翻译：用于烯烃聚合的催化剂组分，其包含紧密混合物：作为Ziegler催化剂的固体组分的组分（A1），其包含钛，镁和卤素作为颗粒形式的主要组分; 和组分（A2），其为选自无机氧化物，无机碳酸盐，无机硫酸盐及其颗粒形式的物理或化学混合物的化合物; 其中组分（A2）以组分（A1）的重量比从0.001至0.5采用，其平均粒径小于组分（A1）的平均粒径。催化剂组分可以是这样的结构，使得颗粒状无机材料组分（A2）粘附或覆盖齐格勒催化剂的固体组分颗粒，从而提高了齐格勒催化剂组分的流动性。
