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.

Optical fibers, and a process for their production

The invention relates to a process for the production of mouldings of crosslinked polymers by processing (moulding) of uncrosslinked copolymers of vinyl compounds and polymerisable silane compounds having 1 to 3 hydrolysable groups to give the desired mouldings and crosslinking of the copolymers in the mouldings by aftertreatment of the mouldings with acidic or alkaline aqueous solutions.

Process for the production of mouldings of crosslinked polymers

The invention relates to mixtures of polyarylene sulphides, maleimides, glass fibres and if appropriate other additives. The mixtures are distinguished by good mechanical properties.
