[ We claim:] [1.] A process for producing a polymer comprising contacting at least one olefin under suitable polymerization conditions with a catalyst system comprising at least one transition metal-containing olefin polymerization catalyst and a solid co-catalyst produced by contacting a solution of an organo aluminoxane having aluminoxy units of the formula [ STR 5 ] wherein R is a hydrocarbyl group, with an organo boroxine, wherein the molar ratio of the boron in the organo boroxine to aluminum in the aluminoxy units of the aluminoxane is in the range of about 1:20 to about 1:3.
