Studien zur Verzweigung von Kettenmolekülen. XIV. Betrachtungen zur Ermittlung von Verzweigungszahlen im Hochdruckpolyethylen aus dem CH3‐Deformationsschwingungsspektrum

Abstract: Carl Schorlemmer" Leuna-Nerseburg, Sektion Chemic, DDR -4 200 Merseburg Die Extinktionskoeffizienten der CH,-Deformationsschwingung von kurzen Kettenverzweigungen in gesattigten polymeren Kohlenwasserstoffen wurden in Abhangigkeit von dcr Seitenkettenlauge an Modellsubstanzen ermittelt. Die Zahl der CHz-Gruppen, die sich zwischen Hauptkette und Methylgruppe der Alkylverzweigung befinden, beeinfluI3t wesentlich die Intensitat der Absorption bei 1378 cm-'. Die Ergcbnisse werden auf die quantitative Auswertung de… Show more

“…The extinction coefficients of the CH3 deformation vibrations of short-chain branches in saturated polymeric hydrocarbons was determined by Reding and L0ve11~~ and Muller et al 25,26 in dependence on the length of side chains in model substances. The number of CH2 groups arranged between the main chain and the methyl group of alkyl branches affects the intensity of the absorption at 1378 cm-'.…”
