(2) The polymer like reaction of the copolymer with a cyclopentadiene compound (III) to give a corresponding copolymer in which some of the exit groups X are substituted by a residue (III'). R -R = H, 1-10C alkyl, optionally substituted phenyl, or the residue group QR R X ; Q = C, CR R C, Ge, or Si, R , R each = H, Me, Et, or Ph, X = halogen, methoxy or ethoxy; and (3) the reaction of the copolymer modified under (2) with a metallocene compound (IV): Cp = optionally substituted cyclopentadienyl, Ti, Zr, or Hf; X = halogen, H, 1-10C alkyl, 1-10C alkoxy or amido, where the various X substituents have different meanings.
