    • PURPOSE:To attain continuous production by forming fibrously a monomer for dissolving a kind of polymer, inserting a monomer whose refractive index is different from that of the polymer of the monomer into its center part, and diffusing this monomer to the outside peripheral part from the center part of the fiber. CONSTITUTION:A polymer A and a monomer B are charged into a cylinder 1, extruded quantitatively by a piston 4, while heating them by a heater 3, mixed homogeneously by a kneading part 2, and thereafter, a strand fiber 6 is obtained from a nozzle 5. In such a case, a monomer C is inserted in advance in the center part of the fiber 6, diffused to the outside peripheral part from the center part of the fiber 6 under a prescribed condition by a heat insulating column 7, and subsequently, led to an active light beam radiating part 8, the monomer B and the monomer C are polymerized and solidified, wound to a winding drum 11 through a nip roller 10, and an object optical transmission body 12 is obtained continuously. In such a case, in order to facilitate the temperature control of the heat insulating column 7 and the polymerization by an active light beam, gas such as air, nitrogen, argon gas, etc. is led in from a gas leading-in hole 9. At the time of quickening the diffusion of the monomer C, an unhardened fibrous object is heated.

    • PURPOSE:To improve productivity by mixing and dissolving a polymer contg. a photocrosslinkable functional group and a monomer having the refractive index different from the refractive index of the polymer, evaporating the monomer from the surface of a molding to impart a continuous concn. distribution of the monomer on the surface from the center and projecting light on the molding. CONSTITUTION:The polymer contg. the photocrosslinkable functional group and the monomer having the refractive index different from the refractive index of the polymer or >=2 kinds of the monomer mixtures contg. said monomer are charged into a cylinder 1, and after the polymer and monomers are uniformly mixed with each other under heating, a strand fiber 6 is formed from a nozzle 5. The monomer is evaporated from the surface of the strand by gas such as air or nitrogen to generate the concn. distribution of the monomer therein. A desired light transmission body 12 is continuously formed by changing and controlling the size, discharge rate, etc., of the strand fiber according to the purpose of use. The light transmission body having the refractive index distribution is thereby formed with good productivity.
