isolatable catalyst system supported, for the polymerization of alk-1-enes of 2 to 10 carbon atoms.

A catalyst system for the polymerization of C2 C10 ALKYL VA COMPOUND metal complexes SIDE IV GROUPS YV the periodic table and an alumoxane compound oligomer, IN WHICH FIRST THE COMPOUND OF COMPLEX METALLIC GROUP SECONDARY IV MIXING YV SYSTEM WITH NEWSPAPER alumoxane oligomer cOMPOUND, AND FINALLY THE cOMPOUND obtained with this applies to a polymer granules. The catalyst systems of the invention are particularly suitable for polymerization ALSO C2 soda manufacture.
