A novel 2,6-bis(imino) pyridine iron(Ⅱ) complex(2,6-bis[1-(4-hydroxy-2,6-dimethylphen-ylimino) ethyl]pyridine iron chloride,1a) was synthesized and investigated as a catalyst for ethylene polymerization in the presence of modified methylaluminoxane as a cocatlyst.The new iron complex displays higher catalytic activity and increases higher molecular mass polyethylene than 2,6-bis[1-(2,6-dimethylphenyli-mino) ethyl]pyridine iron chloride 1b under the identical conditions.The novel complex 1a shows a very high activit(polyethylene mass catalyized by one molar catalyst in one hour) :6.78×10⁶ g/(mol·h).
