Polymerisationsgrad cellulose

Der Polymerisationsgrad gibt die Anzahl der Grundbausteine pro Polymermolekül an. Er ist identisch mit dem Quotienten der mittleren molaren Masse des Polymers und der molaren Masse seiner Wiederholeinheit (der Monomereinheit). Die genaue Zahl kann, außer bei Proteinen, meist nur ein Mittelwert über die betrachtete Probe sein. Dieser Mittelwert wird als Durchschnitts-Polymerisationsgrad (DP) bezeichnet. Für faserbildende Polymere stellt er eine wichtige Größe f… WebDefinitions of BESCHREIBLICH, synonyms, antonyms, derivatives of BESCHREIBLICH, analogical dictionary of BESCHREIBLICH (German)
