The polymers  were analyzed by $^{13}$C-NMR, $^{1 }$H-NMR and GPC to determine  a copolymer composition, copolymer compositional ratio,  Mw and Mw/Mn. The analytical results are also shown in  Table 4.  Copolymer composition and ratio  Mw  Mw/Mn Designation  Synthesis Example 18  10,010  1.91  Comparative  Poly-18
