Abstract
AbstractThe chemical composition distributions (CCDs) of poly(methyl methacrylate)‐graft‐polystyrene samples prepared from the polystyrene macromonomers having methacryloyl and p‐vinylbenzyl end‐groups were determined by high‐performance liquid chromatography (HPLC) based on reversed‐phase and normal‐phase adsorption modes. The CCDs determined by both modes were in good agreement with one another, indicating that the effect of the molecular weight distribution on the CCD is negligible. The results demonstrated the features of the CCDs in agreement with the theoretical predictions and the strong effect of the intrinsic reactivity of the end‐group on the copolymerization reactivity of the macromonomer.
