Procedure

Four olefin polymerization catalyst samples were then prepared by slurrying 0.4 gram portions of each of the activated silica supports made as in the preceeding paragraph with 20 mg. portions of bis(cyclopentadienyl)chromium [II] (chromocene) in about 100 ml. of n-hexane. The slurries were stirred for about 30 minutes to allow the chromium compound to deposit on the activated supports. Control A was prepared as in the preceeding paragraph from silica treated as in A but without adding any (NH4)2SiF6.
