Abstract: PURPOSE:To provide the titled fiber which consists of a polymer or copolymer having a specific structure unit as a core and a polymer having the refractive index lower than the refractive index of the core polymer as a sleeve and which has excellent heat resistance and light transmitting by removing the volatile matter component from the core polymer mixture after the polumn. thereof. CONSTITUTION:The polymer or copolymer contg. >=25wt% structural unit expressed by the formula as the core and the core polymer is formed by soln. polymn. More specifically, the polymn. in the polymn. stage thereof is executed by determining the relations among the polymer P, monomer M and solvent S in the polymn. mixture so as to satisfy P+M+S=100, P>=4, 10 =0.45, supplying the monomer, polymn. initiator, mol.wt. controlling agent and solvent continuously to a polymn. vessel and executing the polymn. under stirring. The monomer which is the structural unit thereof is subjected to the removal of the volatile component in a volatile matter removing stage. The volatile matter component in the polymer is preferably removed down to

Abstract: PURPOSE:To improve discharge capacity characteristic in a high output by setting a specific surface to 4m /g or more of an electrode for a battery containing at least an active material. CONSTITUTION:In order to eliminate an electrode film thickness of discharge capacity of a secondary battery, a specific surface of an electrode is set to 4m /g or more, preferably 5m /g or more and further preferably 6m /g or more. When the specific surface is decreased smaller than 4m /g, an air gap in an electrode agent is decreased, to impede moving an ion in the electrode, and a diffusion controlled ion can not be eliminated. As a positive pole active material, compound oxide of Li is preferable, and LixCoO2(0

Abstract: PURPOSE:To prevent the generation of carbon-fiber fluffs to thereby prevent the occurrence of any internal shortcircuiting in the case where carbon fibers are used as a negative electrode active material, by coating part or the whole of the carbon fibers as electrode active material with resin. CONSTITUTION:PAN-type carbon fibers shaped like fibers, cloths, and the like, cellulose type carbon fibers, pitch type carbon fibers, etc., are used as carbon fibers. These carbon fibers are coated, using a spin-coat method, with thermoplastic or thermosetting resin such as, for example, fluorine resin, olefin resin, epoxy resin, or the like. If the resulting carbon fibers are used as a negative electrode active material, the generation of fluffs from the carbon fibers can be completely prevented. Further, minute shortcircuiting which is attributable to the perforation of the separator due to such fluffs can be prevented. Accordingly, a battery having a high service capacity is obtained with a high efficiency.

Abstract: PURPOSE:To obtain the color filter provided with colored layers having lower thermal colorability by specifying the compds. consisting blank materials for transparent film bodies which constitute the base material layers of the colored layers and the crosslinking agents. CONSTITUTION:The base polymers of the transparent film bodies constituting the base materials of the colored layers to be formed on a substrate consisting of glass, etc., namely the base polymers of a transparent base materials to be colored are constituted mainly of the compds. contg. the constitutional unit expressed by formula and the crosslinking agents. The compds. having the constitutional unit expressed by the formula have a strong cyclic structure and are, therefore, hardly thermally decomposed and hardly oxidized. In addition, the parts of nitrogen exhibit a cationic property in an acidic liquid and are the good exhaustion point in the case of use of the acidic dyes. Inorg. crosslinking agents, such as ammonium dichromate and potassium dichromate and org. crosslinking agents consisting of polyhydric acrylate and methacrylate such ethylene glycol dimethacrylate, pentaerithritol acrylate are preferably usable as the crosslinking agents.
