    • In a process for producing olefin polymers or copolymers which comprises polymerizing olefins or copolymerizing olefins with each other or with dienes in the presence of [A] a solid titanium catalyst component containing magnesium, titanium and halogen as essential ingredients and [B] an organometallic compound of a metal selected from the group consisting of metals of Groups I to III of the periodic table; the improvement wherein said catalyst component [A] is obtained by contacting (i) a magnesium compound in the liquid state with (ii) a titanium compound in the liquid state to form a solid product or first preparing a liquid mixture of the magnesium compound (i) and the titanium compound (ii) and then forming a solid product therefrom, said reaction of forming the solid product being carried out in the presence of at least one electron donor (iii) selected from the group consisting of aliphatic carboxylic acids with 1 to 6 carbon atoms, aryloxy group-containing alcohols, alkylene glycol diethers, aluminum trialkoxides and aluminum triaryloxides, said solid product being not contacted, during or after its formation, with an ester selected from the group consisting of esters of polycarboxylic acids and esters of polyhydroxy compounds.
    • 在制备烯烃聚合物或共聚物的方法中,其包括在[A]含有镁,钛和卤素作为必需成分的固体钛催化剂组分的存在下彼此聚合烯烃或共聚烯烃或与二烯共聚,[B]有机金属化合物 的选自元素周期表第I至III族的金属的金属; 其中所述催化剂组分[A]是通过使(i)液态镁化合物与(ii)液态的钛化合物接触形成固体产物或首先制备镁化合物的液体混合物 i)和钛化合物(ii),然后由其形成固体产物,所述形成固体产物的反应在至少一种选自脂肪族羧酸与1族的电子给体(iii)的存在下进行, 至少6个碳原子,含芳氧基的醇,亚烷基二醇二醚,三烷氧基铝和三芳基铝,所述固体产物在其形成期间或之后不与选自以下的酯接触:多羧酸和酯的酯 多羟基化合物。
