    Abstract: New amorphous, linear polyarylether ketones, with components containing indane, have high glass temperatures and can be easily processed. These and known amorphous, aromatic polyarylether ketones consisting of at least one structural unit of formula -O-A-O-B- (I) are used to manufacture elements for optical systems. The residue A is derived from multinuclear aromatic dihalogen compounds having aromatic nuclei interconnected by CO groups, while B is the residue of mono- or multinuclear diphenols. The polyarylether ketones preferably possess given characteristics with respect to limit viscosity, melt flow index (MFI), refractive index, density, water absorption and Abbe coefficient. They can be used in optical systems such as lenses, prisms, corrected lens systems, achromatic lenses, lighting and projection systems, waveguides, optical coatings and substrates for optical coatings.

    Abstract: A polymer alloy contains at least one cycloolefin polymer and/or at least one polyolefin and a block copolymer as phase promoter, which has different contents of monomers (norbornene derivatives and cycloolefins and/or acyclic olefins) in the individual blocks. To prepare the alloy, the individual polymers are combined and processed at elevated temperature under the action of shear forces.
