20. 2 value and its fraction. However, because of a low percentage of BPO to MA, polymers with a high degree of polymerization (DP) did not dissolve into a good solvent, or even polar ones, such as DMSO or DMAc for measurements of the molecular weight. Therefore, information on the molecular weight of PMA was not obtained, except from a very early stage of polymerization.
