摘要： A polymer is inserted into a cylinder (1) and heated, and a pressure is then applied to the polymer so as to extrude the same in the shape of a fiber from a nozzle (3). In the meantime, a diffusible material is injected from a nozzle (5) into the central portion of a molten liquid of this polymer through a thin-tube cylinder (4), and it is diffused gradually from the central portion of the molten polymer to the circumferential portion thereof as it flows toward a discharge port of the nozzle (3). The material extruded from the nozzle (3) is air-cooled and taken up around a drum (7) via a roller (6). The fiber-like molded product provides a distribution of refractive index varying continuously from the center thereof toward the circumferential portion thereof, and serves as a convergent or divergent plastic light transmitter. Conversely, even when the molten liquid of the polymer is extruded from the nozzle (5), a light transmitter having a region in which a refractive index varies continuously can be obtained. A proper number of the cylinders and various kinds of materials to be supplied to the cylinders can be selected.

摘要： Disclosed is a method of making a graded index polymer optical fibre comprising a bicomponent spinning process employing a core spinning mass and a sheath spinning mass, the core spinning mass and the sheath spinning mass comprising a polymer and a monomer. The monomer in the core spinning mass has a higher refractive index than the monomer in the sheath spinning mass, and the spinning is followed by UV curing. The core and sheath polymers may be, e.g., poly(methyl methacrylate), the core monomer may be benzyl methacrylate, and the sheath monomer may be methyl methacrylate. The core and sheath spinning masses are solutions of the polymer in the monomer having a polymer concentration of from 10 to 50 % by weight.

摘要： A distributed refractive index optical fiber having a multilayer structure of concentric layers made of (co)polymers selected from the group consisting of homopolymers HP1, HP2, ..., and HPn manufactured from two or more kinds of monomers M1, M2, ..., and Mn and having refractive indexes gradually lowering in this order, and one or more kinds of binary copolymer CP of these monomers. Mixed layers of mixtures of the (co)polymers of the adjacent layers are formed between the adjacent layers. The central portion of the optical fiber has the highest refractive index, and the refractive indexes of the optical fiber decreasing gradually toward the outer circumferential portion thereof.

摘要： An improved process, preferably continuous, for the manufacture of gradient refractive index optical objects, wherein a core polymer, which itself may be prepared by a continuous and incorporated process, is passed through a hollow porous surrounding, generally cylindrical so as to obtain and maintain a rounded fiber , through which is fed a second monomer whose polymer has a lower refractive index than the core polymer, so as to swell the core polymer. The swollen polymer with a gradient of swelling by the second monomer from surface to core, is then led to a polymerization unit to complete the polymerization before equilibration of the second monomer throughout the core polymer occurs. The resulting polymers are useful in the preparation of optical fibers and light pipes.

摘要： Plastic layers, containing a polymer A (refractive index: Na) and a refractive index adjusting agent having a reactive index different from that of the polymer A, are applied on an inner surface of a hollow cylindrical body rotating on its axis by using CVD (Chemical Vapor Deposition) or a coating method so as to provide a base material for a plastic optical fiber wherein the refractive index gradually decreases with the distance from the center toward the periphery. The proportion of the polymer A and the refractive index adjusting agent in the plastic layers can be varied so that the reactive index may gradually increase.
