摘要：
Thin layer chromatography with flame ionisation detection (TLC/FID) was applied to determine the chemical composition distribution (CCD) of styrene‐methyl acrylate (S‐MA) emulsion copolymers. The reliability of this method was determined using a well defined high conversion S‐MA solution copolymer. The influence of conversion and monomer water ratio on the emulsion copolymer CCD could successfully be described by a model that uses r values determined in solution, and takes into account the monomer partitioning. The samples were prepared in the presence of 1‐dodecanethiol in order to reduce the molecular mass of the copolymer formed. Not only the conversion part of the total copolymer CCD but also the instantaneous (statistical) part appeared to be important. Copyright © 1990 Hüthig & Wepf Verlag
