摘要:
A deodorant porous polymer having excellent deodorant effects is provided. The deodorant porous polymer is in the shape of substantially uniform particulates or an aggregate thereof, and is obtained by the hydrolysis and polycondensation of at least one alkoxide selected from the group consisting of inorganic alkoxides and metal alkoxides through the use of a sol-gel method. Also provided is a deodorant fibrous material that includes a fibrous substrate and a deodorant porous polymer as mentioned above, which is combined with the fibrous substrate in the physically-combined state and/or the chemically-combined state.
摘要:
A composite substance made of conjugated polymers that contain an inorganic moiety and an organic moiety in their molecule is provided. The conjugated polymers are produced from metal alkoxides and silane coupling agents, or else from metal alkoxides, silane coupling agents, and organic monomers. The conjugated polymers may be fired to give another composite substrate of this invention. These composite substances have both inorganic and organic characteristics, thereby attaining the excellent heat-stability, mechanical strength, resistance to chemicals, and workability.
摘要:
An aromatic composition comprises aromatic substances that are encapsulated and/or clathrated in a matrix of polymer. The polymer includes an inorganic polymer produced from metal alkoxides; a conjugated polymer produced from metal alkoxides and silane coupling agents; and a conjugated polymer produced from metal alkoxides, silane coupling agents, and organic monomers. The aromatic composition has slow-release characteristics, so that the aromatic substances are released over a long period of time. In a method for the production of the aromatic composition, a catalyst for sol-gel methods that comprises an acid or its anhydride and an organic base, and if necessary, irradiation with ultraviolet light and/or an electron beam are used for making the polymer.
摘要:
An anti-fogging coating composition contains (a) an inorganic alkoxide and/or a hydroxyl group-containing polymer formed therefrom by hydrolysis and polycondensation, the inorganic alkoxide being represented by the formula (I): M(OR) n (X) a-n wherein M is an inorganic element selected from the group consisting of Si, Al, Ti, Zr, Ca, Fe, V, Sn, Li, Be, B and P; R is an alkyl group; X is an alkyl group with or without functional groups or a halogen atom; a is a number representing the valence of M; and n is an integer from 1 to a; (b) a polyalkylene oxide, a weight ratio of the polyalkylene oxide to the inorganic alkoxide and/or the hydroxyl group-containing polymer being 100/1-100/150; (c) 0.5 parts by weight or less of an acid catalyst per 100 parts by weight of (a); (d) 0.01-1 part by weight of a base catalyst per 100 parts by weight of (a) + (b); (e) 100-5,000 parts by weight of an organic solvent per 100 parts by weight of (a) + (b) + (d); and (f) a stoichiometric amount or more of water for the hydrolysis of the inorganic alkoxide.

摘要:
A catalyst for sol-gel methods using metal alkoxide comprises a mineral acid or its anhydride and an organic base, said organic base being a tertiary amine that is substantially insoluble in water and soluble in organic solvents. A sol-gel method using the above-mentioned catalyst comprises a step of hydrolyzing a metal alkoxide with a subsequent polycondensation of hydrolyzate thereof using the catalyst, resulting in a polymer containing gel.
