Procedure

The 30 g of a terpolymer of vinyl caprolactam (VCap), dimethylamino propyl methacrylamide (DMAPMA), and 2-hydroxyethyl methacrylate (HEMA) powder was added to 170 g HEMA. GMA (12 g) was added drop-wise with continuous stirring. This solution was heated at 40° C. for one hour. A representative structure for the polymeric reaction is presented below, wherein x+y+z+a=100:
