    Abstract: PURPOSE:To provide a surface light source for which this light transmission body is used and which has high surface brightness and excellent uniformity by constituting the light transmission body of a transparent plate, the medium of which has a refractive index distribution. CONSTITUTION:The transparent plate having the refractive index distribution is exemplified by a flat plate having the refractive index continuously changing in the thickness direction of the plate. Namely, parallel ray of light 4 of light entering from the end edge 2 of the transparent plate 1 having the refractive index distribution are bent to a high-refractive index side and arrive at a high- refractive index surface 3. The effect of the light transmission body is further enhanced by subjecting the high-refractive index surface 3 of the transparent plate 1 to a light diffusion treatment. The method of the light diffusion treatment is exemplified by finishing the surface to a satin state by sandpapering or honing, etc. The light arriving at the high-refractive index surface 3 is diffused by the light diffusion treatment of the surface and is emitted from the low-refractive index surface 5.

    Abstract: PURPOSE:To obtain a molding having high surface hardness and excellent heat resistance by a stage for mixing specific monomers A, B and a stage for polymerizing or curing a mixture composed thereof while or after imparting local polymn. conditions to this mixture. CONSTITUTION:The radical polymerizable monomer A and the monomer which is polymerized by reaction forms (polycondensation reaction, ring-opening- addition, etc.) are mixed to prepare a uniform soln. The uniform soln. is then packed into a container made of glass or resin and the local polymn. conditions are imparted thereto to cause the radical polymn. or the polymn. exclusive of the radical polymn. or curing to solidify the compsn. distribution. The bar- shaped body taken out of a glass tube is colorless and transparent and is cut and polished, by which a transparent plate 1 acting as a convex lens is obtd. The difference in the refractive index between the front surface (low-refractive index surface) 5 and the rear surface (high-refractive index surface) 3 is 0.025 and the refractive index changes continuously. The surface hardness is extremely high.

    Abstract: PURPOSE:To produce a polyarylene sulfide ketone having a high melt stability and a high heat resistance in a short time at a high yield by reacting a specific dihalogenated aryl ketone with an alkali metal sulfide in the presence of a quinone. CONSTITUTION:1mol of a dihalogenated aryl ketone of the formula (wherein R1, R2, R3, and R4 are each a 1-12C alkyl group, an arom. group, an alicyclic group, or a hydrogen atom; and X is a halogen atom) is reacted with 0.95-1.05-mol (in terms of total sulfur content) of an alkali metal sulfide in the presence of a quinone.

    Abstract: PURPOSE:To obtain a resin with high refractive index, excellent impact resistance and no generation of odor caused by hydrolysis by radical-polymerizing a monomer contg. a polyfunctional sulfur-contg. allyl carbonate as an essential component. CONSTITUTION:A monomer contg. at least one of polyfunctional sulfur-contg. allyl carbonates as an essential component is used for preparing a high refractive index resin by radical polymerization. It is pref. that at least one monomer selected from those of formulas I, II and III is used as the carbonate. In formulas I-III, (m) is 0 to 5; (n) is an integer of 0 to 4; R1 and R2 are each hydrogen, a 1 to 5C alkyl group or a sulfur-contg. substituent consisting of alpha S-groups and beta groups selected from CH2, formulas IV and V (wherein S-S is not incorporated; alpha is an integer of 1 to 5; beta is an integer of 1 to 10;); X is O or S; Y is O or S; provided that the case where both X and Y are O is included.
