    Abstract: PURPOSE:To obtain the titled fiber having an excellent optical transmission property in a near infra red range, and lessening a loss, and independent of a vibration absorption of a O-H bind due to a hygroscopicity by using a polymer composed of 20-80mol% a specific fluorine substd. deuterium styrene unit, and 80-20mol% a deuterium (meth)acrylate as a core component. CONSTITUTION:The core component comprises the copolymer composed of 20-80mol% fluorine subtd. deuterium styrene unit shown by formula I, and 80-20mol% deuterium (meth)acrylate shown by formula II as the core component. A number average molecular weight of the copolymer as the core component is preferable to be the range of a few ten thousands-one million, especially 10-50 ten thousands for the optical fiber use. By substituted a hydrogen atom of an aromatic ring contd. in the styrene polymer with the fluorine atom and the heavy hydrogen atom, a hygroscopicity of the obtd. polymer greatly decreases. A vibration absorption strength of the O-H bind due to the hygroscopicity reduces in not only the visible range but also the near infra red range. By using a specific polymer as the core component as mentioned above, the titled fiber has the excellent optical transmission property in from the visible to the near infra-red ranges, and may greatly lessen the increase of the loss under the condition of the high temperature and the high humidity.

    Abstract: PURPOSE:To obtain plastic optical fiber having a core consisting of polymethacrylic ester having superior light transmitting characteristic by prepg. the core by block polymn. at a specified temp. CONSTITUTION:A monomer consisting essentially of methacrylic ester is mixed with additives in a mixing vessel 15 and the mixture 16 is charged to a polymn. vessel 1 and polymerized by circulating a heat medium introduced from an introducing hole 20. The polymn. temp. is elevated gradually from 90 deg.C to 200 deg.C, thus, a polymer having uniform quality and superior transparency is obtd. with conversion as high as >=90% by the block polymn. method. Obtd. core polymer is transferred to a spinning soln. tank 2 where volatile matters are removed out of a vent hole 10. Then, the spinning soln. tank 2 is upset and a piston 4 is pushed down to extrude the core polymer through a die 28. An opening 26 is provided to a die block 24 so as to permit simultaneous extrusion of a sheath polymer. The opening 26 is connected to a sheath polymer extruder 25.
