Title (EN) PHOTO-SETTING RESIN COMPOSITION AND PLASTIC-CLAD OPTICAL FIBERS PRODUCED THEREFROM
(FR) RESINE PHOTO-DURCISSABLE ET FIBRES OPTIQUES RECOUVERTES DE PLASTIQUE PRODUITES A PARTIR DE CETTE RESINE
Abstract:
(EN) A photo-setting resin composition of the invention comprises at least one compound having at least two unsaturated bonds in its molecule and a photo-polymerization initiator and does not contain any compound having only one unsaturated bond in its molecule. Optical fibers having a cladding made of the product of setting of the photo-setting composition have excellent mechanical properties.
(FR) Résine photo-durcissable comprenant au moins un composé possédant au moins deux liaisons insaturées dans sa molécule et une amorce de photo-polymerisation et ne contenant aucun composé ne présentant qu'une liaison insaturée dans sa molécule. Les fibres optiques comportant un revêtement formé par le produit résultant du durcissement de la résine photo-durcissable présentent d'excellentes propriétés mécaniques.
