ABSTRACT:
A supported catalyst component prepared from a support material and an alumoxane, containing 15-40 weight percent of aluminum from the alumoxane (based on the total weight of the support material and alumoxane), said supported catalyst component being obtained by heating said support material and alumoxane under an inert atmosphere at a temperature of from about 85 to about 250.degree. C. for a period sufficient to fix said alumoxane to the support material, to provide a supported catalyst component; wherein not more than about 10 percent aluminum from said alumoxane and present in the supported catalyst component is extractable in a one-hour extraction with toluene at 90.degree. C. using 10 ml toluene per gram of supported catalyst component; and a transition metal compound, and a process for the preparation of the supported catalyst.
