    Abstract: PURPOSE:To obtain a fiber reinforced-material for the plate of a lead acid battery which is highly homogeneously dispersed in a paste made of an active-material powder, by attaching a nonion surface active agent of a polyethylene glycol type to short polyester fibers. CONSTITUTION:A nonion surface active agent of a polyethylene glycol type is attached to short polyester fibers with a length of about 0.5-10mm. and a size of about 1-10 denier to obtain a fiber reinforced-material for the plate of a lead acid battery. The nonion surface active agent of a polyethylene glycol type is, for example, a higher alcohol added with ethylene oxides, an alkyl phenol added with ethylene oxides, a fatty acid added with ethylene oxides, or the like. Here, the amount of the surface active agent is about 0.1-1.0wt% of the short polyester fibers.

    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.
