A 2-L flask was charged with 8.2 g of 3-ethyl-3-exo› tetracyclo[ 4.4.0.l 2’5. l 7’10]dodecanyl methacrylate, 3.6 g of 4-hydroxyphenyl methacrylate, 10.9 g of Monomer 1, 11.5 g of PAG Monomer 1, and 40 g of THF. 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 polymerization initiator was added. The reactor was heated at 60° C., whereupon reaction ran for 15 hours. The reaction solution was poured into 1 L of IPA whereupon white solids precipitated. The precipitate was filtered and dried in vacuum at 60° C., yielding Polymer 4.
