スチレンーブタジエン共重合体の熱分解ガスクロマトグラフィーによる分析

抄録

An analytical method for determining composition of styrene-butadiene copolymers was studied by pyrolysis-gas chromatography.
Relative yield of styrene in copolymer was calculated from the corresponding peaks appearing on the pyrogram at 520°C by making correction for relative sensitivity of the flame ionization detector.
The relationship between the yield (wt%) of styrene and the composition (wt%) of copolymers was linear. The composition of the copolymers was determined by using this relation within 0.6 wt% of mean absolute deviation.
