The invention discloses an olefin copolymerization catalyst system and application thereof. According to the preparation method of the metallocene catalyst, the target product with high yield and high selectivity is obtained by changing the synthesis conditions of the ligand. According to the catalyst system of the olefin copolymer, provided by the invention, the catalyst shown in the formula II is fully activated by utilizing the catalytic active agent, so that efficient olefin copolymerization reaction is completed; meanwhile, the use of benzene solvents is reduced as much as possible. 本发明公开一种一种烯烃共聚催化剂体系及其应用。该茂金属催化剂的制备方法中通过改变配体的合成条件，得到高收率和高选择性的目标产物。本发明提供的烯烃共聚物的催化剂体系，利用催化活性剂对式II所示催化剂充分活化，完成了高效的烯烃共聚反应；同时，还尽可能减少苯类溶剂的使用。
