Abstract: The prodn. of bridged half-sandwich complexes of formula (I) comprises reacting cyclopentadienides of formula (II) with aziridines (III) and then reacting the ligand systems obtd. (IV) with metallating agents and MXn+2. M = Sub-gp. IV or V metal or lanthanide; X = halo, H, 1-10C alkyl, 3-10C cycloalkyl, 6-15C aryl, 7-15C alkylaryl or -OR (with R = 1-10C alkyl, 6-15C aryl, or alkaryl, aralkyl, fluoroalkyl or fluoroaryl with 1-10C alkyl gps. and 6-20C aryl gps.). n = valency of M minus 2; R = H, 1-10C alkyl, 3-10C cycloalkyl (opt. substd. with 1-10C alkyl), 6-15C aryl, (6-20C aryl)-(1-10C alkyl) or -Si(R )3 (with R = 1-10C alkyl, 6-15C aryl or 3-10C cycloalkyl); R -R = as for R , opt. with two adjacent gps. forming a 4-15C cyclic gp.

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 .
