    Description / Table of Contents: Die Modifizierung von Polybutadien durch katalytische und photolytische Spaltung von Dimethyldiazomalonat (dmdm) wird beschrieben. Durch diese Methode werden hochreaktive Carbene erzeugt, die die Bildung von Additions- und Insertionsprodukten bewirken. Die chemischen Strukturen der modifizierten Polymeren wurden durch NMR-Spektroskopie bestätigt. Auch Carbendimere wurden in nicht unbedeutendem Maße gebildet, was vom Molekulargewicht und der Mikrostruktur des Ausgangspolymeren abhängt.
    Notes: Modifications of polybutadienes via catalytic and photolytic decomposition of dimethyldiazomalonate (dmdm) are described. This method pertains to the generation of highly reactive carbenes which give rise to the formation of addition and insertion products. Chemical structures of the modified polymers were confirmed by NMR spectroscopy. It was found that carbene dimers were also formed in a significant extent depending on the molecular weight and microstructure of the initial polymers.
