    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: The present invention relates to soluble catalyst systems for the polymerization of C2- to C10-alk-l-enes, containing, as active constituents, a) a metallocene complex of the general formula I (I) where R1 and R2 are branched C4- to C10-alkyl, 5- to 7-membered cycloalkyl, which may itself be substituted by C1- to C6-alkyl, or are C6- to C15-aryl or aralkyl; R3 to R6 are C1- to C8-alkyl, M is titanium, zirconium, hafnium or vanadium, Y is silicon or germanium, and X is halogen or C1- to C8-alkyl, b) and an open-chain or cyclic aluminoxane compound of the general formula II or III where R7 is C1-C4-alkyl, and m is from 5 to 30. These catalyst systems are particularly suitable for the preparation of polypropylene and copolymers of propylene with lesser amounts of other C2- to C10-alky-l-enes.

    Abstract: Copolymers of polyalk-1-enes (a) with one functional chain-end per macromolecule and polyalk-1-enes (b) with several functional gps. along the main chain are claimed (I); (I) are obtd. by reaction of the functional chain-ends of (a) with the functional gps. in (b). Also claimed is a process for the prodn. of (I), by reaction of (a) with (b) at 0-300 deg. C and 1-100 bar. More pecifically, (a) are polypropylene homopolymers (homo-PP), copolymers of propylene with small amts. of other 2-8C alk-1-enes, ethylene homopolymers (PE) or copolymers of ethylene with small amts. of 3-8C alk-1-enes, pref. homo-PP, with the functional chain-end contg. at least one atom of B, N, O, Si, P, S and/or Hal; (b) are grafted homo-PP or co-PP, grafted homo-PE or co-PE, or grafted polyisobutylenes, pref. contg. in-chain COOH, COOH derivs., amine or alcohol gps. USE/ADVANTAGE - (I) are useful for the prodn. of film and moulded prods. (claimed); also claimed are polymer alloys based on (I), and moulded prods. made from copolymers (I) or polymer alloys contg. (I) as main components. The invention provides polyolefins with long chain branches, which are readily combined with many different polymers to produce alloys, film and moulded prods. (since the chemical compsn., degree of branching and side-chain compsn. of (I) can be modified acccordingly); copolymers (I) have relatively high impact strength and high rigidit
