TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: (I) comprises solid or liquid additives comprising group formed by polymers, salts, fillers comprising (non)modified (grafted) silica, aluminas, titanium oxides, aluminum oxides, titanates, (non)modified clays, micas, ceramics, zeolites, fibers and surfactants. (I) comprises at least one lithium salt.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The epoxide group is aromatic, cycloaliphatic, heterocyclic, or aliphatic epoxides, optionally substituted by aliphatic, cycloaliphatic, aromatic or heterocyclic group or elements comprising fluorine or bromine, where the main chain or substituents optionally comprising carbon and/or hydrocarbon chain segments comprises other elements than carbon, hydrogen and oxygen and groups that are chemically reactive. The amino group is organic derivatives comprising at least two primary amine functions, or at least one primary amine and one or more secondary amine functions or one or more tertiary amine functions, aromatic, heterocyclic, cycloaliphatic or aliphatic amines optionally substituted by aliphatic group, where the main chain or substituents optionally comprises elements comprising silicon, fluorine, sulfur, chlorine or bromine. The cation of the ionic liquid is tetraalkylammonium, cations from aromatic cyclic amines (di-, tri- and tetraalkylimidazolium, alkylpyridinium) or from aliphatic cyclic amines (di and tri alkyl piperidinium, dialkylpyrrolidinium, dialkylmorpholinium), tetraalkylphosphonium and trialkylsulfonium, and anion of the ionic liquid is halides (fluoride ion (F-), chloride ion (Cl-), bromide (Br-) and iodide ion (I-)), nitrate, phosphate, sulfate, perchlorate ion (ClO4)-, tetrafluoroborate ion (BF4)-, hexafluorophosphate-ion (PF6)-, hexafluoroarsenate ion (AsF6)-, dicyanamide ion (N(CN)2)-, tricyanomethanide ion (C(CN)3)-, perfluorobutane sulfonate ion (C4F9SO3)-, trifluoroacetate ion (CF3CO2)-, triflate ion (CF3SO3)-, trifluoromethanesulfonimide ion (N(CF3SO2)2)-, amide ion (CF3CONCF3SO2)-, tris(trifluoromethanesulfonyl) methanide (C(CF3SO2) 3)-, acetate ion (CH3CO2)- or formate ion (HCO2)-. The stoichiometric ratio of epoxide/amine (ratio of products of the functionality by the concentration of each monomer) is 0.25-1.75. Preferred Process: The step of polymerization is carried out by heat treatment. The epoxide group and amine group such as the polyepoxide-polyamine group is produced in epoxy-amine mixture after polymerization carried out to a glass transition temperature (Tg) at less than or equal to 150 degrees C. The epoxide group and the amino group are chosen such that the polyepoxide-polyamine group is produced in epoxy-amine mixture after heat treatment at Tg of less than or equal to 50 degrees C. EXAMPLE - Typical composition comprised (in wt.%) of: Araldite DY-C (RTM: Diglycidylether of cyclohexane dimethanol) (41.25); Jeffamine EDR 148 (RTM: Polyetheramine) (8.75); and 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (50).
