The main kinetic laws governing 4-methylpentene-I (MP) polymerization and copolymerization with propylene (P) on the catalytic system TiCI 3 + (C2Hs)gAIC1 between 30 and 70 ° were studied. The MP homopolymerization is kinetically first-order in monomer and TiCl> The effective activation energy is 8'
## Abstract The dialkyl(monocyclopentadienyl)hafnium acetamidinates, Cp\*Hf(R)~2~[N(Et)C(Me)N(__t__‐Bu)] [Cp\*=η^5^‐C~5~Me~5~, R=Me (3a) and __i__‐Bu (3b)], were prepared through either ‘one–pot’ carbodiimide insertion or two‐step salt elimination protocols starting with commercially available Cp\*
It is shown that the system TiC14-(C2Hs)2AICI-(C6Hs)2Mg is highly efficient and very promising as a catalyst of the filling of polyethylene during the polymerization with inorganic fillers (chalk, marble powder, perlite, kaolin and dolomite). The preliminary activation of the filler, the formation t
