METHOD FOR PRODUCTION OF RADICALLY POST-CURED POLYMERS BY ADDITION OF REACTIVE ANHYDRIDES

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.
