NOVEL TETRAARYLBORATE COMPOUND, CATALYST COMPOSITION COMPRISING SAME, AND METHOD FOR PREPARING ETHYLENE HOMOPOLYMERS OR COPOLYMERS OF ETHYLENE AND alpha-OLEFIN BY USING SAME

The present invention relates to a novel tetraarylborate compound, a catalyst composition comprising same, and a method for preparing ethylene homopolymers or copolymers of ethylene and alpha-olefins by using same. In detail, the tetraarylborate compound has the excellent thermal stability and can be completely dissolved in an aliphatic hydrocarbon-based solvent, thereby facilitating operation of commercial processes and effectively inducing activation of a single-site catalyst. When used as a catalyst activator, the tetraarylborate compound allows high catalytic activity and can provide high molecular weight ethylene homopolymers and ethylene-based copolymers selected from copolymers of ethylene and alpha-olefin, and the like. 本发明涉及新的四芳基硼酸盐化合物、包含其的催化剂组合物、以及用于通过使用其制备乙烯均聚物或乙烯和α烯烃的共聚物的方法。详细地，四芳基硼酸盐化合物具有优异的热稳定性并且可以完全溶解在基于脂族烃的溶剂中，从而促进商业过程的操作并有效地诱导单位点催化剂的活化。当用作催化剂活化剂时，四芳基硼酸盐化合物允许高催化活性并且可以提供高分子量乙烯均聚物和选自乙烯和α烯烃的共聚物的基于乙烯的共聚物等。
