摘要： The invention relates to a precursor compound of an alkaline earth metal or a rare earth metal aluminate of formula: a(M1O).b(MgO).c(AI2O3) or a(M2O1.5).b(MgO).c(AI2O3), where M1 = an alkaline earth metal and M2 = yttrium or a combination of cerium and terbium and a, b et c are either whole numbers or not and obey the relationships: 0.25 = a = 4; 0 = b = 2 et 0.5 = c = 9, crystallized in the form of a transition alumina comprising essentially spherical and chemically homogeneous particles. Said particles have pores the average diameter of which is less than 10 nm. The above is obtained by a method in which a liquid mixture is formed comprising compounds of aluminium and other elements present in the composition of the precursor, said mixture is dried by atomisation and the dried product calcinated at a temperature between 700°C and 950°C inclusive. An alkaline earth metal or a rare earth metal aluminate is obtained by subsequent calcination of the product obtained.

摘要： The invention relates to a method of preparing a block copolymer, the first block of which is a polymer or a copolymer having at least one diene and the second block of which is a polymer with a polar monomer. The inventive method is characterised in that: first, the polymerisation or the copolymerisation of the first block is carried out in the presence of a catalyst comprising the product of the reaction of a rare earth alcoholate and an alkylating agent selected from among organolithiums, organomagnesiums, organozincs, organoaluminiums and borons; and, secondly, the copolymerisation of the polar monomer is performed with the first block in the presence of the same catalyst. The invention also relates to a block copolymer consisting of a first block comprising a polmyer or a linear copolymer having at least one diene and a second block comprising a polymer presenting several hydroxy, epoxy and/or alkoxysilyl functions. Said copolymers can be used as compatibilisers in an elastomer matrix comprising a mineral filler.

摘要： The invention concerns an aqueous colloidal dispersion based on at least a lanthanide compound and a complex-forming agent having a pK (cologarithm of the dissociation constant of the complex formed by the complex-forming agent and the lanthanide cation) higher than 2.5. Said dispersion can further comprise a compound of at least an element selected among the groups IVa, Va, VIa, VIIa, VIII, Ib, and IIb of the periodic table. The method for preparing the dispersion consists in starting with an aqueous mixture comprising at least a lanthanide salt, optionally a salt of one said element, and the complex-forming agent; adding a base to the resulting mixture and heating the mixture, whereby the dispersion is obtained. The dispersion can be used on a substrate as anticorrosive agent, in a cosmetic composition, in catalysis, for preparing polymer films, in lubricants or in ceramics.
