Polyethylene resins having improved environmental stress crack resistance, stiffness and impact resistance is made by a process comprising feeding both a chromium oxide catalyst and a silyl chromium catalyst into a polymerization reactor. The chromium oxide catalyst and the silyl chromium catalyst are on separate supports. The chromium oxide catalyst is 25–50 weight percent and the silyl chromium catalyst is 50–75 weight percent of the total weight of catalyst. The catalysts may be added separately or as a single mixture.
