摘要：
The present invention relates to a catalyst for oligomerization of ethylene, comprising a functionalized solid support; a ligand immobilized on the solid support by chemical bonding, wherein the immobilized ligand has the structure (R1)(R2)P—N(R3)—P(R4)—Y-support or (R1)(R2)P—N(R3)—P(R4)—N(R5)—P(R6)—Y-support, wherein R1, R2, R3, R4, R5 and R6 are independently selected from aliphatic group, aryl group, amino group and trimethylsilyl group and Y is the functional group of the support or a derivative thereof; and a chromium compound reacted with the ligand; and to a method for its preparation and a process for oligomerization of ethylene utilizing the catalyst.
