R -R = H or 1-8 C alkyl; n = 2-10; R = 1-6 C alkyl, Ph or benzyl; m = 2-50; M = Ti, Zr, Hf, V, Nb or Ta; R , R = H, halo, 1-10 C alkyl or alkoxy, 2-10 C alkenyl, 6-10 C aryl or aryloxy, 7-40 C aralkyl or alkaryl, or 8-40 C aralkenyl; R , R = mono- or poly-nuclear hydrocarbon residue which can form a sandwich structure with M ; R = -X-, -X-M R R -, -X-C(R )2-, -CR R -, -O-X-, -CR R -CR R - or -BR -; X = -M R R -; M = Si, Ge or Sn; R -R = H, halo, 1-10 C alkyl, fluoroalkyl or alkoxy, 6-10 C aryl or fluoroalkyl, 2-10 C alkenyl, 7-40 C aralkyl or alkaryl, or 8-40 C aralkenyl; or R +R or R +R or R +R may form a ring with their linking atom. Also claimed are COC polymers obtd. by this process, esp. with a content of more than 40 mole% norbornene units. Also claimed are extruded parts, injection moulded prods. and polymer alloys contg. the above COC polymer(s).

Abstract: Syndio-iso block polymers of 1-olefins containing molecular chains in which syndiotactic and isotactic sequences are present are obtained if a catalyst which comprises a bridge-containing chiral metallocene of the formula I and an aluminoxane is used for the polymerisation of the 1-olefins. Some of the polymers have rubber-like properties.

Abstract: Process for the preparation of ethylene polymers The preparation of polyethylene and ethylene-1-olefin copolymers in the suspension or gas phase process with the aid of metallocene/aluminoxane catalysts whose metallocene component is a bridged biscyclopentadienyl complex offers particular advantages. Depending on the structure of the complex, the use of these complexes gives, with high activity, products in a very broad molecular-weight range and permits the production of very varied grain morphologies of the products, such as high and low bulk density, extremely small and extremely large mean grain diameters and various grain shapes. The variety of grain morphologies which can be achieved opens up various possibilities for the use of such polyethylene powders in sintering processes.
