The determination of copolymer composition as a function of molecular weight by preparative gel permeation chromatography and comparison to the rapid stop‐and‐go GPC/IR method

The determination of the copolymer composition as a function of molecular weight by preparative gel permeation chromatography (GPC) for a poly(styrene‐co‐vinyl stearate) sample is described. These results were compared to data obtained on the same copolymer by the previously described rapid stop‐and‐go GPC/IR method of analysis of copolymer composition as a function of molecular weight and found to be in good agreement.
