Composition especially for use as a capacitor film comprises a polymer (especially a thermoplastic polyester) and a material of high relative dielectric constant

A polymer film contains a material of high relative dielectric constant, the dielectric constant of the film (epsilonR) being greater than epsilonpolymer + 0.5 where epsilonpolymer is the relative dielectric constant of the starting polymer. An independent claim is also included for manufacture of t...

Beschreibung
Zusammenfassung:	A polymer film contains a material of high relative dielectric constant, the dielectric constant of the film (epsilonR) being greater than epsilonpolymer + 0.5 where epsilonpolymer is the relative dielectric constant of the starting polymer. An independent claim is also included for manufacture of the film by (co)extrusion, stretching and thermofixing. Eine Folie aus einem thermoplastischen Polymer, z. B. thermoplastischer Polyether wie PET und PEN, welche 5 bis 70 Gew.-% eines Materials mit hoher relativer Dielektrizitätskonstante, z. B. Bariumtitanat, enthält, eignet sich als Katalysatorfolie zur Herstellung von Katalysatoren mit verbesserter Kapazitätsausbeute. Für die relative Dielektrizitätskonstante Epsilon R der Folie gilt Epsilon R > Polymer + 0,5, mit Epsilon Polymer gleich relativer Dielektrizitätskonstante des Ausgangspolymers.
