    • The present invention relates to a guide rail for a refrigerator. A guide rail for a refrigerator according to the present invention comprises a rail body having a back face to be brought into close contact with a side surface of an inner case defining a storage space of the refrigerator; a guide portion provided in the rail body so that the guide portion extends in front of a guide rib formed to be elongated in a fore and aft direction on the side surface of the inner case, thereby guiding the movement of a receiving container to be accommodated in or taken out from the storage space; and a seating space provided in the rail body so that a portion of the guide rib is inserted into the seating space when the back face of the rail body is brought into close contact with the side surface of the inner case. According to the present invention, there is an advantage in that it is possible to secure the operational reliability and the durability of a product.

    • A solid titanium complex catalyst for polymerization and copolymerization of ethylene is prepared by the process comprising: (1) preparing a magnesium solution by reacting a halogenated magnesium compound with an alcohol; (2) reacting the magnesium solution with an ester compound having at least one hydroxyl group and a boron compound having at least one alkoxy group to produce a magnesium composition; and (3) producing a solid titanium catalyst through recrystallization by reacting the magnesium composition solution with a mixture of a titanium compound and a haloalkane compound; and optionally reacting the solid titanium catalyst with an additional titanium compound. The solid titanium complex catalyst for polymerization and copolymerization of ethylene according to present invention exhibits high catalytic activity and can be advantageously used in the polymerization and copolymerization of ethylene to produce polymers of high bulk density, narrow particle size distribution and small amount of fine particles.
    • 一种用于乙烯聚合和共聚的固体钛络合物催化剂是通过以下方法制备的:(1)通过使卤代镁化合物与醇反应制备镁溶液; (2)使镁溶液与具有至少一个羟基的酯化合物和具有至少一个烷氧基的硼化合物反应以制备镁组合物; 和(3)通过使镁组合物溶液与钛化合物和卤代烷烃化合物的混合物反应,通过重结晶制备固体钛催化剂; 并且任选地使固体钛催化剂与另外的钛化合物反应。 用于本发明的乙烯聚合和共聚的固体钛络合物催化剂显示出高的催化活性,并且可以有利地用于乙烯的聚合和共聚合以产生高堆积密度,窄粒度分布和少量细颗粒的聚合物。
