1.2‐dinitrile polymers. II. Homopolymers and copolymers of diphenylmaleonitrile, meso‐ and dl‐diphenylsuccinonitrile, phthalonitrile

Abstract

Homopolymers of diphenylmaleonitrile, mesoand dl-diphenylsuccinonitrile as well as copolymers with fumaronitrile and phthalonitrile have been prepared in the presence of free radical initiators of medium high decomposition temperature. The polymers were isolated as black infusible powders, however, completely soluble in acidic solvents. A simple technique for preparing phthalocyanine and derivatives of tetrazaporphin also evolved Gorn this work. Three new tetrazaporphin derivatives have been prepared. ZUSAMMENFASSUNG:Homopolymere von Diphenylmaleinsaurenitril, mesound dl-Diphenylbernsteinsaurenitril, sowie deren Copolymere mit Fumarsaurenitril und Phthalsaurenitril wurden unter Verwendung eines Radikalstarters mit relativ hoher Zersetzungstemperatur hergestellt. Die Polymeren sind unschmelzbare, schwarze Pulver, die sich jedoch in Sauren vollstandig losen.Eine einfache Methode zur Darstellung von Phthalocyanin und Derivaten des Tetrazaporphins war ein Nebenergebnis dieser Arbeit. Drei neue Tetrazaporphinabkommlinge wurden dargestellt. * ) Part I. cf. ref.2).H gauche anti rneso-DPSNLater, the pure gauche form of meso-DPSN (mp 243-244OC, lit.6) 24O-24l0C) was also prepared from the, as received, material.

Polymerization and characterization of nitrile‐terminated diacetylene materials

“…The cyano group has been polymerized by cationic, anionic, radical and coordination catalysts. ''- 23 Recent interest in these polymers has also focused on their use as potential electrically conductive materials. However, the measured conductivities from various nitrile polymers were not as high as were anticipated (10-8-10p6 52-' cm-').…”
