Abstract

The invention concerns a process for preparing a polymer composition, that is free-radical/photochemical and thermal curing epoxide-methacrylate and/or isocyanate-methacrylate adhesives in broadest terms, dental/medical adhesives, and dental restoratives. Furthermore the dual curing epoxide-methacrylate and/or isocyanate-methacrylate adhesives can be used in the optical industry, in optoelectronics and microelectronics, for example for the adhesion of complicated optical components in the combination glass/glass, glass/metal. Advantageous is the small shrinkage during polymerization and the good mechanical properties in combination with the possibility of step-wise or one-step polymerization.
