A novel insitu-process allows the manufacturing of very special solventfree, non-aqueous Polyurethane-Acrylates. Which principle is guiding the synthesis and what properties can be achieved?

Impact strength is one of the most fundamental properties of the polymer matrix of a high-performance adhesive in order to withstand high levels of stress. Another characteristic of materials with different elasticity is the ultimate elongation of the adhesive matrix. The ultimate elongations, as well as the impact strength, are conventionally increased by incorporating rubber components in an otherwise brittle matrix. This concept is, for example, applied in crash-optimised epoxy adhesives which have been proven for structural bonding in the automotive industry or in methacrylate adhesives, known as toughened acrylics and used for high-strength, wear-resistant metal/metal- or hard plastic bonding. This method of impact strength modification is especially successful in case of easily soluble and...
