Procedure
The same procedure as described in Example 3 was employed in this example. Specifically, about 100 g of PGMEA solution containing 25 wt. percent of methacrylate-hydroxystyrene copolymer (CMM, 50/50, from Maruzen) was added in with about 35 mg of oxalic acid and 11.4 g of MOCH. The reaction was quenched with 4 g of basic active aluminum oxide and showed 41 mole % protection on the phenol groups of the PHS polymer.
