In the present invention, for optical fiber cladding manufactured as a base material of a poly(meth)acrylate copolymer with a minimized ether linkage (-COC-) containing oxygen bonds with high affinity with water (H 2 O) Through the resin composition, by utilizing the reactive side chain (Functional Side Chain) provided in the poly (meth) acrylate polymer structure constituting the copolymer, a fluorinated carbon chain for low refractive properties, or epoxy or By supporting the selective bonding of an acrylate reactor or a silane reactor for high adhesion to the glass core, the low refractive index fundamentally required for optical fiber cladding is met, while the water resistance against moisture penetration is significantly improved. At the same time, to provide a resin composition for optical fiber cladding that can be effectively applied to high-power optical fiber lasers by increasing output stability by retaining high glass transition temperature characteristics. |
