Abstract :
A series of novel aluminoxanes, ethyl-isobutylalulminoxanes (EBAO) modified with n-butaneboronic acid, phenylboronic acid and 4-fluorobenzeneboronic acid are synthesized. The ethylene polymerization activity of [diacetyl-bis(2,6-diisopropylanil)] NiBr2(1)/different aluminoxanes were investigated. It is found that boronic acid greatly affects the catalytic activity of modified EBAO. Bulky substituted boronic site of EBAO improved ethylene polymerization activity of nickel complex.
