    摘要： The adherence of an individual fibre embedded in a polymer matrix is determined by a drawing experiment in which the fibre is drawn out of the polymer matrix and simultaneously the pertaining force-distance diagram is registered. To this end a test sample consisting of the polymer matrix with the individual fibre embedded therein is manufactured by melting down a quantity of polymer present in granular or powder form on an object holder, the individual fibre is dipped into the molten polymer mass and the polymer mass is subsequently cooled down below the melting point. Subsequently the object holder with the test sample adhering thereto is brought into a force-distance measuring device, and the free end of the fibre is fixed to a chucking device moveable in the direction of the fibre. In the drawing experiment, the drawing force acting on the fibre is converted into corresponding electrical signals by the force transducer, and evaluated, and simultaneously the distance covered by the chucking device is converted into corresponding electrical signals by the distance transducer, and evaluated.

    摘要： Air-drying unsaturated coating compositions are obtained by reacting at least 60% of the epoxide groups of a polyepoxid with more than one epoxid group per molecule(a) with 0.01 to 0.5 NH-equivalents, based on one epoxide group of ammonia, an aliphatic or cycloaliphatic primary or secondary amine and subsequently(b) with 0.99 to 0.5 carboxyl equivalents, based on one epoxide group of acrylic or methacrylic acid.The reaction products may be mixed with solvents and/or copolymerizable monomers and are preferably hardened in the presence of known photoinitiators with the aid of energy radiation.Their particular advantages are their stability in the dark and that they also harden very quickly in the presence of atmospheric oxygen.Preferred substrates are paper and cardboards.
