摘要

利用二维相关凝胶渗透色谱(2D GPC)分析了0.5和2.0 M HCl·h2o催化下正辛基三乙氧基硅烷(OTES)的溶胶-凝胶转变过程的复杂细节。结果表明，二维GPC相关光谱的特征直接反映了聚合过程中反应或相互作用的动态变化。

Two-dimensional correlation gel permeation chromatography (2D correlation GPC) study of the sol–gel polymerization of octyltriethoxysilane. HCl-concentration dependence

Two-dimensional correlation gel permeation chromatography (2D GPC) was used to elucidate intricate details of the initial ten minutes of the sol–gel transition of n-octyltriethoxysilane (OTES), catalysed by 0.5 and 2.0 M HCl·H 2 O. The results demonstrate that the features of 2D GPC correlation spectra directly reflect the dynamic variation of reactions or interactions present during the polymerization process.
