Abstract
The synthesis of an aryl alkyl azo diisocyanate and a model azo urea i s described. From the azo diisocyanate new azo polyureas were created by interfacial polyaddition. Molecular weights M(n) in the range of 60 00 to 9000 were determined by gel permeation chromatography (GPC). Pho tolysis and thermolysis of both, model compounds and polymers, were st udied by UV-spectroscopy and differential scanning calorimetry (DSC), respectively, and the results were compared with those of similar azo amides. Photochemical polymer degradation was followed by GPC.
