Both mesoporous (MCM‐41) and spherical silica supported palladium‐based diimine catalysts were prepared and their behaviors on ethylene polymerization were studied. The results showed that good catalytic activities could be reached with cocatalyst sodium tetraarylborate. Ethylene polymerization with palladium‐based catalysts in mesoporous silicas (MCM‐41) gave polymers with less branched chains than those obtained with the corresponding homogeneous catalyst.
