Comparative Polymer  1  was analyzed for  composition by $^{13}$C- and $^{1 }$H-NMR and for Mw and Mw/Mn  by GPC.  [0212]  Comparative Polymer 2 was obtained by the same  procedure as in Synthesis Example 2-1 except that 2-(dim› ethylamino)ethyl methacrylate was used instead of Mono› mer  1.  Comparative Polymer 2 was analyzed for composi› tion by $^{13}$C- and $^{1 }$H-NMR and for Mw and Mw/Mn by GPC.  [0213]  Comparative Polymer 3 was obtained by the same  procedure as in Synthesis Example 2-2 except that Monomer  2 was omitted and l-methyl-1-cyclopentyl methacrylate was  used instead of l-methyl-1-cyclohexyl methacrylate.
