Procedure

To a 2 liter glass vessel equipped with; reflux condenser, stirrer, means of temperature control, 300 g deionized water and 300 g propan-2-ol were charged then heated to a gentle reflux. A monomer mixture of dimethylaminoethyl methacrylate (134.6 g) and ethyl acrylate (200 g) was fed into the reactor over an approximate time frame of 3 hours. Sodium persulphate solution (3.4 g in 125 g of water) was fed concurrently with the monomer over a similar time period. When feeds were a propan-2-ol azeotrope was then distilled from the reactor, followed by neutralization with acetic acid (41.2 g).
