Notes:
Summary Gel permeation chromatography of. isotactic PMMA has been performed on a Chromatograph linked to a 500 MHz 1H NMR spectrometer. 1H NMR spectra of good resolution and high S/N ratio were collected over the entire Chromatographic peak. The Mn of the polymer sample can be directly determined by intensity measurements of the proton signals due to the endgroup and monomeric units, since the polymers used were prepared by the living polymerization initiated by t-C4H9MgBr. A good linear relation was obtained between the log(Mn) and elution time.
