    摘要: A method of preparing an ionic conducting gel in solid form, known as ionogel. The method includes a step of mixing an ionic liquid with at least one molecular precursor containing at least one hydrolyzable group, if necessary in the presence of an acid, such as a carboxylic acid. The mixture is subsequently left to stand for one or more days until a gel is formed by polycondensation of the molecular precursor(s). The gel contains the aforementioned ionic liquid and can be set, in particular in transparent monolithic solid form.

    摘要: The present invention relates to the synthesis of optionally alkoxylated polyorganosiloxane (POS) resins by non-hydrolytic condensation. The object is to provide a process which offers the possibility of controlling the crosslinking. This object, inter alia, is achieved by the process according to the invention, which makes provision for carrying out a non-hydrolytic condensation reaction between alkoxysilyl units (Mo1) and halogenosilyl units (Mo2), both of which are carried by identical or different silanes, in the presence of a catalyst of the Lewis acid type, said condensation reaction generating essentially .tbd.Si--O--Si.tbd. linkages and coproducts XR (X=halogen). In this process, the target POS comprise siloxy units D, T and/or Q, or perhaps M, the catalyst is selected from metal compounds or mixtures thereof based on at least one metal belonging to group IIIB, IVB or VB of the periodic table, and the reaction temperature and the initial ratio OR/X are adjusted so that condensation takes place substantially exclusively between the units Mo1 and Mo2, with extreme minimization of secondary condensation between two alkoxy units OR to give the by-product R.sub.2 O.
