Popis:	This paper critically examines the scope and limitations of state-of-the-art chromatographic techniques (GPC, GC, HPLC) for separating and analyzing the composition, molecular weight, and molecular weight distribution of acrylate and styrene based polyether macromonomers. Of the three chromatrographic techniques investigated, HPLC is found to be the most useful technique for macromonomer analysis, being applicable over a wide molecular weight range and having favorable selectivities towards the many macromonomer components. Macromonomer purity, n-mer distribution, and molecular weight can be derived from a single chromatographic run. In addition, conformational information can be obtained.
