摘要: 合成了几种新型的含氯丙基的取代聚硅氧烷,其热稳定性可达300~325℃,能较好地分离非极性和中等极性化合物。当固定相的苯基含量高达50%时,用8%的DCP能使其有效交联。

Abstract: The novel chloropropylpolysiloxanes were synthesized and used for gas chromatographic stationary phase. This new, moderately polar stationary phases exhibit higher-thermal stability (300~325℃) and can be used to separate non-polar and moderately polar compounds——n-alkanes, alkyl-benzenes, halogenated alkanes, esters and ketones. The McReynolds constants of these stationary phases are apparently higher than that of QV-17 and very similar to that of QF-1. The thermal stability and separation power of the alternating condensation polymers are better than that of the random copolymers. The stationary phase with 50% phenyl content could be crosslinked by 8% dicumyl peroxide. The vinyl group attached to the main chain may facilitate the crosslinking.
Key words: Chloropropylpolysiloxanes, Gas chromatographic stationary phase, Condensed polymer
