PHOTO-CROSSLINKABLE LIQUID COMPOSITION FOR PLASTIC OPTICAL FIBRE

摘要

The invention relates to a photo-crosslinkable liquid composition (A1) which is intended to form an at least partially-crosslinked polymer material for the production of a plastic fibre (F). The inventive composition contains: a photoinitiator, at least one photoreactive compound comprising a first photoreactive functional group which is selected from acrylates and methacrylates, and a photoreactive polymer comprising a second photoreactive functional group. According to the invention, at least one of either the aforementioned compound or polymer is at least monofunctional, while the other is at least bifunctional. The invention is characterised in that the second photoreactive functional group is an acrylate that is different from a methacrylate.
