- W1990125923 abstract "Evidence is given that, when solutions of diene monomers and anthracene in tetrahydrofuran are reacted with alkali metal and subsequently titrated with linking agents such as alkyl dihalides, copolymers are formed; they contain the 9,10-dihydroanthracene adduct and the diene in the same proportion as in the original solution. The structures of these copolymers have been elucidated by NMR spectroscopy and the mechanism of formation is discussed. On démontre que des solutions dans le tetrahydrofuranne de monomères diéniques et d'anthracène réagissant d'abord avec un métal alcalin et titrées ensuite par des agents de couplage tels que les dihalogénures d'alcoyle, conduisent à la formation de copolymères; ceux-ci contiennent le composé dihydro 9,10-anthracène et le monomère diénique dans la même proportion que dans la solution de départ. La structure de ces copolymères a été résolue par spectroscopie RMN et on présente une discussion concernant leur formation. Si forniscono delle prove che soluzioni di monomeri di diene e antracene in tetraidrofurano formano copolimeri qualora esse vengano fatte reagire con metalli alcalini e successivamente titrati con agenti leganti come per es dialidi alchilici. copolimeri che contengono l'addotto 9,10-diidroantracene e il diene nelle medesime proporzioni che nella soluzione originale. Si è spiegata la struttura di tali copolimeri mediante spettroscopia NMR e se ne è discusso il meccanismo di formazione. Es wird gezeigt, daβ bei der Reaktion von Dienmonomeren und Anthracen in Tetrahydrofuran mit Alkalimetallen und anschlieβender Reaktion mit Dihalogenalkylen Copolymere erhalten werden. Diese enthalten das 9,10-Dihydroanthracenaddukt und das Dien im gleichen Verhältnis wie in der ursprünglichen Monomerenlösung. Die Strukturen dieser Copolymeren wurden mithilfe der NMR-Spektroskopie aufgeklärt und der Reaktionsmechanismus wird diskutiert." @default.
