Mode opératoire

A 10% solution of poly(AMD/DMAEA.MeCl/EA) was prepared as follows: 13.87 parts of 53.58% aqueous acrylamide (AMD), 25.31 parts of a 80% aqueous solution of ethacryloxyethyltrimethylammonium chloride (DMAEA.MeCl), 2.33 parts of ethyl acrylate (EA), 0.3 part EDTA, 258.16 parts of deionized water and 0.030 parts of VA-044 were added to a suitable glass vessel. The solution was sparged with nitrogen gas and stirred for about one hour at ambient temperature. The nitrogen sparge was changed to a nitrogen purge, and polymerization was initiated thermally by raising the temperature of the solution to 44° C. Stirring and heating were continued for about 21 hours to give a clear, viscous solution of poly(AMD/DMAEA.MeCl/EA) having a standard viscosity of about 2.0 centipoise.
