Abstract:
PCT No. PCT/FR90/00074 Sec. 371 Date Sep. 28, 1990 Sec. 102(e) Date Sep. 28, 1990 PCT Filed Jan. 26, 1990 PCT Pub. No. WO90/08644 PCT Pub. Date Aug. 9, 1990.A process for producing scintillating optical fibres consisting in dissolving in a monomer having aromatic cycles, in particular vinyltoluene or styrene, 1-phenyl-3-mesityl-2-pyrazolin (PMP) doping molecules and a chain transfer agent, especially glycoldimercapto acetate, in heating the mixture so as to cause it to polymerize and to effect the final sheathing and stretching of the polymer so as to produce the optical fibres. The process of the invention enables fibres to be obtained which have a very small diameter (in the region of 30 to 50 microns) with a reduced molar extinction in a proportion exceeding 100 in relation to conventional scintillating fibres; it also totally suppresses diaphotic phenomena when the fibres are arranged to form a beam.
