[0187] Synthesis of Polymer 8 

[0188] A 2-L flask was charged with 6.1 g of Monomer 8, 8.4 g of l-methyl-1-cyclopentyl methacrylate, 3.4 g of 3-hydroxystyrene, 11.0 g of PAG Monomer 2, and 40 g of THF as 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 was added. The reactor was heated at 60° C., whereupon reaction ran for 15 hours. The reaction solution was poured into 1 L of isopropyl alcohol for precipitation. The precipi› tated white solid was collected by filtration and vacuum dried at 60° C., yielding Polymer 8. Polymer 8 was analyzed for composition by $^{13}$C- and $^{1}$H-NMR and for Mw and Mw/Mn by GPC.

[0189] Synthesis of Polymer 9 

[0190] A 2-L flask was charged with 5.5 g of Monomer 9, 8.4 g of l-methyl-1-cyclopentyl methacrylate, 3.4 g of 3-hydroxystyrene, 11.0 g of PAG Monomer 2, and 40 g of THF as solvent. The reactor was cooled at - 70° C. in nitrogen atmosphere, after which vacuum pumping and nitrogen blow were repeated three times.
