اٍنهاء سلسلة (بالإنجليزية: Chain termination) هي أي تفاعل كيميائي يتسبب في تشكيل (Reactive intermediate) ضمن (chain propagation) في سير البلمرة ويؤدي بفعالية إلى التوقف. (ar) Eine Abbruchreaktion, auch Kettenabbruch, ist eine chemische Reaktion, die eine Kettenreaktion beendet. Normalerweise verbinden sich bei einer Abbruchreaktion zwei Radikale (z. B. 1a und 1b) zu einem Molekül 2: Die Radikale können kombinieren (siehe oben) oder disproportionieren, dadurch wird die Kettenreaktion formal beendet: (de) Chain termination is any chemical reaction that ceases the formation of reactive intermediates in a chain propagation step in the course of a polymerization, effectively bringing it to a halt. IUPAC definition Chemical reaction in which a chain carrier is converted irreversibly intoa non-propagating species without the formation of a new chain carrier. (en) La terminación de cadena es una reacción química que cesa la formación de intermediarios reactivos provenientes de la etapa de propagación de la cadena en el curso de una reacción radicalaria, deteniéndola. (es) De laatste fase in een chemische kettingreactie wordt terminatie genoemd. Deze fase bestaat uit stappen waarbij reactieve tussenproducten worden gedeactiveerd of vernietigd. Zo wordt een eind aan de keten gemaakt. (nl) A terminação da cadeia é uma reação química que cessa a formação de intermediários reativos provenientes da etapa de no curso de uma reação de radicais, detendo-a. É uma etapa muitas vezes útil na indústria de reações orgânicas, em especial, na produção de polímeros. (pt) |
