Abstract: -1- of the disclosure Bulk polymerization using specific metallocene catalysts for the preparation of cycloolefin polymers Polymers of polycyclic olefins, such as, for example, norbornene or tetracyclododecene, or copolymers of polycyclic olefins with cycloolefins and/or 1-olefins are obtained without ring opening, in high space-time yield, with a high cycloolefin incorporation rate and at in- dustrially favorable polymerization temperatures, by bulk polymerization in which a catalyst is used which comprises an aluminoxane and a stereorigid chiral metal- locene compound of an element from groups IVb to VIb, where the hydrocarbon radicals forming the sandwich structure are different.

Abstract: polymer electrolytes are described that comprise a sulfonated aromatic polyether ketone, e.g. of the formula II where A is from 0.2 to 1, c is from 0 to 0.8, and a + c = 1. The polymer electrolytes are prepared by dissolving an aromatic polyether ketone in 94-97% by weight sulfuric acid and adding a sulfonating agent, e.g. oleum, to the solution until the sulfuric acid concentration is from 98 to 99.9 % by weight.

Abstract: The present invention relates to a process for the preparation of a polyolefin by polymerisation of at least one olefin in the presence of a stereorigid metallocene compound containing, as ligands, at least two substituted or unsubstituted cyclopentadienyl groups bonded to one another via a monocyclic or polycyclic ring system, where at least one cyclopentadienyl group is fused to the monocyclic or polycyclic ring system.

Abstract: A fibre-reinforced cycloolefin polymer material comprises from 1 to 99 % by weight of reinforcing fibres, in particular glass fibres, and from 99 to 1 % by weight of a cycloolefin copolymer built up from a) at least one (polycyclo)olefin derived from norbornene, for example tetracyclododecene, and b) at least one olefin selected from monocycloolefins having 4 to 12 carbon atoms (VII) and/or the group of acyclic olefins (VIII). in which R , R , R and R are identical or different and are an hydrogen atom or a C1-C8-alkyl radical. VII is preferably ethylene. In the cycloolefin copolymer molecule, the monomer units of the (polycyclo)olefin are separated from one another by monomer units of the cyclic olefins VII and/or the acyclic olefins of the formula VIII.

Abstract: The disclosed oriented polyolefin film contains at least one voided layer. The voided layer contains an amorphous voidinitiating polymer which, after orienting, is present as a separate particle inside the void. In the process for producing the polyolefin film, a molten blend comprising an olefin polymer and the amorphous polymer is extruded through a die at an extrusion temperature above the glass temperature or Vicat softening point of the amorphous polymer, the resulting film is drawn off on one or more rollers, and is then subjected to stretch orientation, followed optionally by thermofixing and a surface treatment.
