Kurzfassung englisch:
The main limitation of UV-induced crosslinking reactions is related to the hindering of UV-light penetration towards thickness of the formulations, which limits this polymn. technique in the prepn. of thick composite materials. This limitation has been overcome by the introduction of a Radical Induced Cationic Frontal Polymn. (RICFP) process1-3. The suggested mechanism put together the so-called Radical Induced Cationic Polymn. (RICP) with Frontal Polymn. (FP). UV-cured bulk epoxy composites were successfully produced by Radical Induced Cationic Frontal Polymn. (RICFP); it was shown that the FP is started by the dissocn. of a radical, thermal initiator (RTI) promoted by the heat released during surface UV-induced cationic ring-opening polymn. Subsequently, the carbon-centered radicals are oxidized to carbocations by the presence of the iodonium salt PAG in a RICP mechanism.
