CATALYST FOR OLIGOMERIZATION OF ETHYLENE, METHOD FOR PREPARATION THEREOF AND PROCESS FOR OLIGOMERIZATION USING IT

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 (RJ(R2)PEN(R3)EP(R4)Y SUPPORT OR (RI)(R2)PEN(R3)EP(R4)N(RS)P(RJYSUPPORT, WHEREIN R1 R2, R3, R4, R5 AND F?6 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.
