[0203] Synthesis of Polymer 9 

[0204] A 2-L flask was charged with 0.6 g of Monomer 8, 8.4 g of l-methyl-1-cyclopentyl methacrylate, 3.8 g of 3-hydroxystyrene, 11.0 g of PAG Monomer 2, and 40 g of THF solvent. The reactor was cooled at - 70° C. in nitrogen atmosphere, after which vacuum pumping and nitrogen blow were repeated three times. The reactor was warmed up to room temperature, whereupon 1.2 g of AIBN ~as added. The reactor was heated at 60° C., whereupon react10n ran for 15 hours. The reaction solution was poured into 1 L ofIPA for precipitation. The precipitated white solid was collected by filtration and vacuum dried at 60° C., yielding Polymer 9. Polymer 9 was analyzed for composition by $^{13}$C- and $^{1}$H-NMR and for Mw and Mw/Mn by GPC.

## Synthesis Example 9 

[0205] Comparative Polymer 1 was obtained by the same procedure as in Synthesis Example 1 except that Monomer 1 was omitted. Comparative Polymer 1 was analyzed for composition by $^{13}$C- and $^{1}$H-NMR and for Mw and Mw/Mn by GPC. 

[0206] Comparative Polymer 2 was obtained by the same procedure as in Synthesis Example 2 except that Monomer 2 was omitted and l-methyl-1-cyclopentyl methacrylate was used instead of l-methyl-1-cyclohexyl methacrylate. Com› parative Polymer 2 was analyzed for composition by $^{13}$C› and $^{1}$H-NMR and for Mw and Mw/Mn by GPC.
