The solution of poly(trimethylsilyl methacrylate [48 mol %]-b-benzyl methacrylate [37 mol %]-b-ethoxy-triethylene glycol methacrylate [15 mol %]) was refluxed for 12 hr with 150 mL of 0.03M methanolic tetrabutyl-ammonium fluoride and an additional 100 mL of THF. After evaporation in a rotary evaporator under reduced pressure, the residual polymer was dried for 48 hr in a vacuum oven at 50° C. to give 186.3 g of poly(methacrylic acid [48 mol %]-b-benzyl methacrylate [37 mol %]-b-ethoxy-triethylene glycol methacrylate [15 mol %]). 1H NMR analysis of the product showed that no trimethylsilyl ester groups remained.
