    摘要： The invention relates to storage-stable, quick-curing epoxide resin moulding materials containing:A. pre-adducts containing aromatic constituents and free epoxide groups and formed from epoxide resins and polyamines,B. pre-adducts containing free amino groups and formed from polyamines containing cycloaliphatic or heterocyclic groups with polyglycidyl compounds, as curing agents, andC. mineral or organic pulverulent or fibrous fillers, with the epoxide resin pre-adducts and the curing agents softening between 45.degree. and 120.degree.C, and melting 5.degree. to 30.degree.C above the softening point, and the resin pre-adducts and the curing agents being present in the moulding materials predominantly in the form of particles separated from each other.The moulded articles are distinguished by very good stability to solar and UV rays, and retain their original colour to a very considerable extent even after prolonged irradiation.

    摘要： Prepolymers of alkali metal silicates and/or alkaline earth metal silicates and metal oxides, which can be used as molding compositions, preferably compression molding compositions, for the production of compression-molding laminates or of insulating sheets, are obtained by a method wherein a mixture of solid alkali metal silicates and/or alkaline earth metal silicates, and/or aqueous solutions of such silicates, with or without addition of water, and of divalent to tetravalent metal oxides, the ratio of metal oxide to silicate in the mixture being from 1:1 to 1:9, expressed in parts by weight of solids, and the homogenized mixture having a water content of from 10 to 50% by weight, based on the total amount of mixture, is allowed to pre-react in the temperature range of 10.degree. to 50.degree. C. until the water content of the mixture has decreased by from 0.1 to 25% by weight and a product which is sufficiently tough and dry to permit comminution is obtained, and this product is comminuted and then heated at temperatures of up to 120.degree. C. until the prepolymer obtained has a water content of from 20 to 2% by weight.
