    Abstract: PROBLEM TO BE SOLVED: To obtain a new mesoporous silica having respectively specific surface area and volume of the mesopores and useful as a molded article, a catalyst or a catalyst carrier by converting a silica precursor in a water-containing reaction medium containing a polymer dispersion liquid. SOLUTION: The mesopore of this mesoporous silica has a specific surface area of >=500m /g and a volume of >=1.0mL/g. The maximum size of the pare diameter distribution of the mesopore is preferably >=3nm. The obtained silica is preferably baked. The polymer dispersion liquid is preferably a cationic aqueous polymer dispersion liquid stabilized with a cationic emulsifier and/or a cationic comonomer (emulsifying agent or α,β-ethylenic unsaturated monomer having quaternary amine or ammonium structure). These emulsified polymers can be produced preferably by using a free-radical polymerization initiator having a cationic group.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject catalyst, capable of producing a polymer having a high molecular weight by using a middle-sized pore molecular sieve as a carrier. SOLUTION: This catalyst has a middle-sized molecular sieve as a carrier. Further, the molecular sieve contains oxides of elements of Si, Be, B, Al, Ga, In, etc., and/or Ce, has an aluminosilicate structure, especially a silicate structure and 1.5-25nm middle-sized pores, and contains 0.1-10wt.% chromium content. In order to obtain the catalyst, it is preferable that the middle-sized pore molecular sieve in a solvent is brought into contact with a chromium compound (e.g.; chromium oxide), then the solvent is removed and the catalyst is calcined at 400-1200 deg.C.

    Abstract: A solid (I) containing aluminIum oxide (Al2O3) is claimed, which is obtained by a process comprising contacting Al2O3 precursor(s) (II) with template compound(s) in a liquid medium, in which the template is a dendrimeric molecular nano-system (III) or mixture of 2 or more of these. Also claimed are: (i) the method of producing (I) in this way; and (ii) the use of (III) as template in the production of (I). Preferably The nano-system contains a nitrogen (N), phosphorus (P) or carbon (C) atom or a mixture of 2 or more of these as branch point. (I) also contains element(s) selected from sodium, potassium, calcium, magnesium, beryllium, boron, gallium, indium, silicon, germanium, tin, lead, bismuth, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, rhenium, iron, cobalt, nickel, ruthenium, copper, zinc, cadmium, mercury and cerium.
