(Dimethylamino)ethyl methacrylate → Methacrylic Acid

Participants

Reaction Steps

The solution of poly(trimethylsilyl methacrylate [48 mol %]-b-2-phenylethyl methacrylate [30 mol %]-co-2-dimethylaminoethyl methacrylate [7 mol %]-b-ethoxytriethylene glycol methacrylate [15 mol %]) was treated with 45 mL of 0.03 M methanolic tetrabutylammonium fluoride and heated at reflux for 8 hr. The solution was evaporated in a rotary evaporator under reduced pressure. The residual polymer was dried for 24 hr in a vacuum oven to give 59 g of poly(methacrylic acid [48 mol %]-b-2-phenylethyl methacrylate [30 mol %]-co-2-dimethylaminoethyl methacrylate [7 mol %]-b-ethoxytriethylene glycol methacrylate [15 mol %]). 1H NMR analysis of the product showed that no trimethylsilyl ester groups remained.
