COMPOSITE SEMI-FINISHED PRODUCTS, MOLDED PARTS PRODUCED THEREFROM, AND DIRECTLY PRODUCED MOLDED PARTS BASED ON HYDROXY-FUNCTIONALIZED (METH)ACRYLATES AND URETDIONES THAT ARE CROSS-LINKED IN A THERMOSETTING MANNER

摘要

Polymerization, for example at room temperature or at up to 80° C., gives rise to thermoplastics or thermoplastic prepregs which can subsequently be subjected to a forming operation. The hydroxy-functionalized (meth)acrylate constituents and the polyols can subsequently be crosslinked with the uretdiones already present in the system by means of elevated temperature. In this way, dimensionally stable thermosets or crosslinked composite components can be produced.
