Plastic optical transmission body

Abstract

Abstract PURPOSE:To improve the heat and solvent resistances by combining a core with a clad having a lower refractive index than the core and by using a water cross- linked product of a copolymer consisting essentially of a methacrylate-base monomer and an unsatd. silane compound as the material of the core. CONSTITUTION:The core is combined with a clad having a lower refractive index than the core. The core is made of a water cross-linked product of a copolymer consisting essentially of one or more kinds of methacrylate-base monomers and an unsatd. silane compound. The copolymer contains about 0.2- 20wt% units of the unsatd. silane compound. The copolymer is formed into the prescribed shape of the core as an optical transmission body, and it is cross- linked by condensing the silane groups. A plastic optical transmission body having high heat and solvent resistances can be obtd.
