Procedure

A solution of bis(cyclopentadienyl)chromium in toluene was prepared, which solution was then added to a predetermined amount of silica (Grace· 532 product), dehydrated under an inert atmosphere at a temperature of 815° C. for 16 h, so that the final chromium content is 1% by weight. The toluene was then removed under reduced pressure. The bis(cyclopentadienyl)chromium was then sublimed under reduced pressure onto the silica support for 5 hours. Return to atmospheric pressure was carried out under dry nitrogen and the catalyst obtained was stored with oxygen and water excluded.
