摘要： PURPOSE:To permit mass production of titled bodies and arrays having stable quality by using not a partly polymerized agar-like gel base material but a nearly completely polymerized network polymer as a base material for diffusing a monomer. CONSTITUTION:The monomer Ma forming the transparent network polymer Pa having a refractive index Na is nearly completely polymerized to form the bar- or fiber-shaped base material. This base material is held in the liquid monomer Mb which forms the polymer Pb having the refractive index Nb different from the refractive index Na or in an atmosphere contg. the gaseous, mist-like monomer Mb and thereafter, or while said monomer is held therein, the monomer is heated to diffuse the monomer Mb from the surface of the base material into the inside thereof and completely polymerize the same. The monomer is harder and is less likely to be deformed then the partially polymerized transparent gel base material and, therefore, said monomer is extremely easy to handle in the stage of production. Since this base material has high dimensional stability as well, the mass production of the homogeneous light transmission body made of the synthetic resin having excellent optical characteristics is permitted.

摘要： PURPOSE:To obtain a plastic light transmitting body having continuously changing refractive index by producing a parent material as a medium for diffusing a monomer from an almost perfectly linear polymer obtd. by selectively polymerizing only one functional group of a bifunctional monomer Ma by anionic polymn. CONSTITUTION:Anionic polymn. is initiated at a low temp. in a soln. of a monomer Ma where radical polymn. is hardly occurred. When the product is poured into a large amt. of methanol contg. a radical polymn. inhibitor at RT after terminating the polymn., a linear polymer Pa 1 produced by the polymn. of only one of the functional groups is deposited. A parent material Pa 2 is obtd. by cast molding, extrusion molding, or wet spinning, etc. the polymer after fuildizing the linear polymer Pa 1. The molded Pa 2 is heated while holding it in a liquid monomer Mb or in an atmosphere contg. the monomer Mb allowing the monomer Mb to diffuse into the inside of the parent material Pa 2 from its surface to cause copolymn. By subjecting the copolymer to sufficient heat treatment, a network polymer having a completed three- dimensional structure is formed. By this process, a plastic light transmitting body having high mechanical characteristics, weather resistance, suitability to polishing, and continuously changing refractive index from the surface to the inside is obtd.

摘要： PURPOSE:To obtain the high refractive index and Abbes number of the titled composition, and to reduce the contraction of the titled composition at the time of molding in a casting polymerization by polymerizing a monomer contg. a specific tricyclodecane derivatives. CONSTITUTION:The titled composition is formed by polymerizing the monomer contg. the tricyclodecane derivatives shown by formula I. The titled composition is formed by polymerizing the tricyclodecane derivative, preferably, in the presence of a radical polymerization initiator. The titled composition can be formed by jointly using the tricyclodecane derivative and an another monomer to improve the physical and the mechanical properties of the resin article of the molded body, such as the impact resistance, the contraction property and the dyeability, or to change the optical balance of the refractive index and the Abbes number. The monomer is not specified, if the monomer has the radical polymerization property, and the transparency of the obtd. polymer does not injure, and is exemplified by an acrylic acid etc., such as methyl methacrylate and cyclohexyl methacrylate.

摘要： PURPOSE:To obtain a light transmitting body having extremely high precision of shape and stable quality by coating the inside wall surface of a vessel with a copolymer of monomers having the highest monomer reactivity ratio or with a material having high affinity with the copolymer. CONSTITUTION:Inside wall surface of a polymn. tube 1 is coated previously with an acrylic F-contg. resin paint. The polymn. tube 1 is transferred from above downward with a fixed speed through a constant temp. chamber 2A. Thus, the monomer mixture in the tube 1 is heated and irradiated with light successively from its foot end. Copolymn. occurs at the bottom of the polymn. tube 1. Although the volume of the polymn. tube 1 is contracted by the polymn., no void is formed in the polymn. tube by the continuous feed of the monomer mixture from an unpolymerized part at the top of the polymn. tube 1. In accordance with the movement of the polymn. tube 1, the polymerizing part is transferred upward successively, and finally the whole monomer mixture in the polymn. tube 1 is solidified.

摘要： PURPOSE:To improve the abrasion, weathering and chemical resistance of a plastic surface, by forming a plasma polymer film of a specified gas mixture on the plastic surface through a plasma polymer film of an aromatic compound. CONSTITUTION:An undercoat is formed on a plastic surface by plasma polymerization of an aromatic compound. The purpose protective film is formed by forming a topcoat on the above undercoat by plasma polymerization of a gas mixture of an aliphatic hydrocarbon and/or an aromatic hydrocarbon with hydrogen and/or argon. Examples of the aromatic compounds used includes benzene, styrene, naphthalene and substituted derivatives thereof. The mixing ratio of said gas mixture is 1:0.5-1:500 (in terms of a ratio among gas feed rates), and when the feed rate of the aliphatic hydrocarbon and/or the aromatic hydrocarbon is smaller than that of hydrogen and/or argon gas, a film of good abrasion resistance can be usually obtained.

摘要： PURPOSE:To enable phase matching by a simple method using a material which is incapable of angle matching by superposing a thin film waveguide of an optically nonlinear material on a thin film optical waveguide and giving a tapered change of thickness to both or one of the waveguides. CONSTITUTION:The wave-guided light through a waveguide 2 in the perpendicular direction and through a gradient formed by a light input and output coupler prism 3A, 3B mounted on a thin film optical waveguide 2 with a slant thickness gradient on a flat substrate 1 is mode-coupled with an optical waveguide 4 of a nonlinear optical crystal of 2-methyl-4-nitroaniline(MNA), etc. having higher refractive index than the waveguide 2 between the coupler prism 3A, 3B, and converted to the second light harmonic light in the waveguide 4 and mode-coupled to the original waveguide again, and outputted together with the fundamental wave light from the prism 3B. The second light harmonic light is isolated from the outputted light. When the incident light 5 is shifted so as to result highest received light intensity, thus, phase matching of the light is possible simply by using MNA, etc. which is incapable of angle matching.
