    Abstract: Catalyst systems for the polymerisation of olefinically unsaturated compounds, containing (A) a metallocene complex of a Sub-Group 4, 5 or 6 metal, (B) a metallocenium ion-forming compound and (C) a sterically hindered organic Lewis base. Also claimed is a process for the production of polymers by linking at least two unsaturated monomers at 0-450 degrees C and 0.1-500000 kPa in presence of a catalyst system as above. Preferably component (B) is a 1-10C aluminoxane, and component (C) is a sterically hindered hydroxyaryl or aryloxyaluminium compound, preferably a phenol, naphthol or hydroxyanthracene derivative in which the ring positions directly adjacent to the hydroxy or aluminoxy groups are substituted with bulky groups.

    Abstract: A process for the production of polymers of 2-12C alkenes at -50 to 300 degrees C and 0.5-3000 bar in presence of a catalyst system, with the addition of a compound of formula H-M )R (I); where M = B, Al, Ga, In or Tl; R , R = H, 1-10C alkyl, 6-15C aryl, or alkaryl or aralkyl with a 1-10C alkyl and a 6-20C aryl group, or 5- to 7-membered cycloalkyl (optionally substituted with 1-10C alkyl); or R + R may form a 4-15C cyclic group. Preferably R and R together form part of a 4-15C bicyclic group; M = boron. The catalyst system contains (A) a metallocene complex and (B) a metallocenium ion-forming compound. A metal compound of formula M )r(R )s(R )t (IV) may also be added; M = alkali or alkaline earth metal, or a Sub-Group III metal, i.e. B, Al, Ga, In or Tl; R = 1-10C alkyl, 6-15C aryl, or alkaryl or aralkyl with 1-10C alkyl and 6-20C aryl groups; R , R = as for R , or also halogen or 1-10C alkoxy; r = 1-3; s, t = 0-2; r + s + t = the valency of M .
