OPTICAL RESIN COMPOSITION AND USE THEREOF

摘要

A substance for refractive index regulation which has satisfactory compatibility with a noncrystalline fluoropolymer (A); and a light-transmitting material comprising a composition of the polymer (A) combining high transparency with heat resistance, especially an optical fiber of the refractive-index distribution type. The substance for refractive index regulation comprises a compound (B) selected between perfluoro(1,3,5-triphenylbenzene) and perfluoro(1,2,4-triphenylbenzene). The light-transmitting material comprises as a matrix the polymer (A) containing substantially no carbon-hydrogen bond.
