In a process for preparing a metal-containing supported catalyst or a metal-containing supported catalyst component by impregnation of a support material with an impregnation solution comprising the metal component, the impregnation solution flows through the support material.

Preparation of a metal-containing supported catalyst or a supported catalyst component by impregnation of a support material

The polymerization of olefins is carried out in the presence of catalysts comprising at least one complex of a transition metal with a tridentate macrocyclic ligand which additionally bears at least one functional substituent and, if desired, one or more activator compounds. A catalyst system comprising at least one transition metal complex as set forth above and at least one activator compound is also provided.

Method for the polymerization of olefins

Substituted monocyclopentadienyl, monoindenyl, monofluorenyl and heterocyclopentadienyl complexes of chromium, molybdenum or tungsten in which at least one of the substituents on the cyclopentadienyl ring carries a donor function which is bonded rigidly, not exclusively via sp -hybridized carbon or silicon atoms, and a process for the polymerization of olefins.

Monocyclopentadienyl complexes of chromium, molybdenum or tungsten

Gas phase fluidized bed method and ethylene homo- and copolymers obtained using said method

A semicrystalline propylene polymer composition with good suitability for producing biaxially oriented films and prepared by polymerizing propylene, ethylene and/or C -C -1-alkenes, where at least 50 mol % of the monomer units present arise from the polymerization of propylene. Also described is the use of the semicrystalline propylene polymer composition for producing films, fibers or moldings, the films, fibers and moldings made from these compositions, biaxially stretched films made from the semicrystalline propylene polymer compositions, and also a method for characterizing the semicrystalline propylene polymer compositions.

Semicrystalline propylene polymer compositions with good suitability for producing biaxially oriented films

The invention relates to a method for producing a supported catalyst which contains metal, or a supported catalyst constituent which contains metal by impregnating a supporting material with an impregnating solution containing the metal constituent, whereby the impregnating solution flows through the supporting material.

Method for producing a supported catalyst

Propene terpolymers with a low extractable portion

A sealable coextruded film is made from at least one outer layer and from at least one base layer, where the outer layer is composed of a propylene terpolymer comprising from 80 to 99.5 mol % of structural units derived from propylene, from 0.2 to 15 mol % of structural units derived from ethene or from a C -C 1-olefin (I) and from 0.3 to 15 mol % of structural units derived from another C -C 1-olefin (II) different from the C -C 1-olefin (I), and where the propylene terpolymer has been prepared using metallocene catalysts.
