摘要：

Recently, a two-dimensional chromatography analysis of stereoregular poly(ethyl methacrylate) (PEMA) appears to provide a promising solution in characterizing the distribution of the two molecular characteristics independently. This method was based on the assumption that tacticity has negligible effect on the hydrodynamic volume of polymer chains and size exclusion chromatography (SEC) can separate the polymer according to the molecular weight only. This paper examines the tacticity effect on SEC retention by constructing SEC calibration curves using the PEMA samples with very narrow molecular weight distribution.
