Ziegler
Ziegler : (1) A process for polymerizing ethylene under moderate temperatures and pressures, catalyzed by a mixture of titantanium tetrachloride and a trialkyl aluminum such as triethyl aluminum. (2) A process proposed for making tetraethyl lead by electrolyzing the molten complex of ethyl potassium with triethyl aluminum, KAl(C2H5)4, using a lead electrode
