Reaction Steps

6-Chlorohexyl methacrylate ethylene glycol bismethacrylate co-polymer (4.1 meq Cl/g, approximately 1.9 molar % cross-linking) (c.f. Example 17) (14.1 g) was reacted with sodium bromide (6 g) and ethyl bromide (63.2 g) in N-methylpyrrolidone (200 ml) at 65° for 6 days. The slurry was then sieved and the fraction <53 μM discarded. The remaining polymer was washed with water, methanol, acetone and diethylether and dried under vacuum for 16 hours to give 6-bromohexyl methacrylate ethylene glycol bismethacrylate co-polymer (14.97 g, 3.47 meq Br/g, no Cl detected).
