Abstract

Optical fibres, and a process for their production, are described which comprise tubular plastic cladding and a core of a polymer whose refractive index is at least 1% greater than that of the cladding material. The core is obtained from a polymerisable mixture which comprises compounds containing epoxy groups, of which at least 10% by weight are siloxanes containing epoxy groups.
