    Abstract: The preparation of epoxy resin compositions which comprise glycidyl ethers comprising cyclohexyl groups and have a low oligomer content is carried out by distillation of compositions which are obtainable by ring hydrogenation of compounds of the general formula (I) where —X— is —CR2—, —CO—, —O, —S—, —SO2—, the radicals R are each, independently of one another, H, C1-6-alkyl, C3-6-cycloalkyl, in which one or more H atoms can be replaced by halogen, the radicals R′ are each, independently of one another, C1-4-alkyl, halogen, the indices n are each, independently of one another, 0, 1, 2 or 3, and subsequent reaction of the hydroxyl groups with epichlorohydrin, in thin film evaporators or short path evaporators at a temperature in the range from 150 to 270° C. and a pressure in the range from 0.001 to 1 mbar.

    Abstract: The invention relates to an epoxide resin composition as a matrix component for sheet molding compounds (SMCs) and/or bulk molding compounds (BMCs), comprising a resin component comprising at least one epoxide resin and a hardener component comprising at least one imidazole compound and at least one latent hardener. In said epoxide resin composition, the amount of the imidazole compounds used lies in a range of 0.007 to 0.025 mol per mol of epoxide groups of the entire composition, and the total amount of optionally contained primary amine groups does not exceed a proportion of 0.09 mol per mol of epoxide groups of the entire composition. The invention further relates to a fiber-matrix semifinished-product composition (SMC or BMC composition), comprising said epoxide resin composition as a matrix component and short reinforcing fibers suspended therein and having an average length of 0.3 to 5.0 cm. The fiber-matrix semifinished-product composition can be produced by mixing the constituents, whereupon the composition thickens. The thickened product thus obtained (semisolid fiber-matrix semifinished product) is characterized by a comparatively short maturing time and comparatively long handleability. The invention further relates to the corresponding semisolid fiber-matrix semifinished product, in particular the semisolid SMC, and the corresponding hardened fiber-matrix semifinished product, in particular the hardened SMC. Finally, the invention further relates to a screening method for identifying epoxide-resin-based compositions that are suitable for use as a thermosetting matrix for the production of SMCs.
