    摘要: The aim of the invention is to obtain prepregs on the basis of duroplastic, oleochemical matrices that can be stored at room temperature. To this end, a fiber material that preferably contains natural fibers is contacted with a matrix material at temperatures of 40 to 80 °C in the presence of a suitable catalyst and the fiber material impregnated with the matrix is cooled to temperatures of 30 °C and less. The matrix material is chosen from a fatty substance with at least 12 C atoms that contains epoxide and/or hydroxyl groups, a cross-linking agent and a catalyst, and the matrix material has a Brookfield viscosity of 600 to 1400 MPa at temperatures of 40 to 80 °C.

    摘要: The invention relates to a method for production of radically post-cured polymers. In a first stage, at least one, or several compounds (a), which are the reaction products of epoxidised fatty acid esters and /or epoxidised triglycerides with acrylic acid and/or methacrylic acid, are converted into the corresponding polyurethane (a*) and said polyurethane (a*) is subsequently radically post-cured, in a second stage, in the presence of at least one radical initiator (b), with the additional proviso that, in the second stage, a combination of compounds (a*) with one or several compounds (c) are used, where the compounds (c) are chosen from the group of the reactive anhydrides. The polymers thus obtained are excellent matrix agents for composite materials.

    摘要: The invention relates to a method for producing radically post-cross-linked polymers. In a first step, one or more compounds (a) that are the reaction products of epoxidized fatty acid esters and/or epoxidized triglycerides with acrylic acid and/or methacrylic acid are converted to the corresponding polyurethanes (a*) by reacting them with aliphatic and/or aromatic isocyanates, and the polyurethanes (a*) thus produced are radically post-cross-linked in a second step in the presence of at least one radical initiator (b). The polymers obtained are excellent matrix materials for composite materials.
