24. 2- protons was found to be 1:16 on the basis of the integration of the spectra. If we assume only one end of the polymer chain is vinyl group (the other end would be bromine), the above end group analysis would imply a polymer with an average repeating unit of 8, which corresponds to a number average molecular weight of 6300. The polymer would have an average repeating unit of 16 if both polymer chain ends are vinyl groups. However, elemental analysis showed a significant amount of bromine in the polymer (1.07%). Again, if we assume one polymer chain end is bromine, the polymer would have a molecular weight of 7500 (calculated by 79.9/0.0107) based on the bromine content inside the polymer
