SYNDIOSPECIFIC POLYMERIZATION OF PROPYLEN E - 2-SUBSTITUTED AND 2,7-SUBSTITUTED METALLOCENE COMPLEX OF THE (C(13)H(8-N)R(N)CR(N)(')C5H4)MCL(2) (N=1,2 R=ALKOXY, ALKYL, HAL R(')=ME, PH M=ZR, HF)

Seventeen new catalyst. precursors for the syndiospecific polymerizati on of propylene are presented. The new metallocene complexes are subst ituted in the positions 2 and 7 of the fluorenlidene fragment by MeO-, halogen-, alkyl- and aryl groups. The focus is directed on effective new synthetic routes to substituted fluorenes and the preparation of B e catalyst precursors. In addition first polymerization results are re ported.
