The reaction product of an incompletely desolvated ethereal Grignard reagent and TiCI,,, when employed with a trialkylaluminium cocatalyst, possesses catalytic activit~ for the polymerization of ethylene, of some two orders of magnitude (on the basis of Ti) greater than that of traditional TiCI 3 ca
## Abstract Chromocene deposited on silica supports of high surface area forms a highly active catalyst for polymerization of ethylene. Polymerization is believed to occur by a coordinated anionic mechanism previously outlined. The catalyst formation step liberates cyclopentadiene and leads to a ne
