Reaction Steps

In the case of hydrophilic monomers of acid type, an at least one 1M solution of base, such as a salt of hydroxonium ion (OH−), an amine, ammonia, a carbonate (CO32−) salt or a hydrogencarbonate (HCO3−) salt, is added to the vigorously stirred solution. In the case of hydrophilic monomers of amine type, an at least 1M solution of acid, such as hydrochloric acid, hydrobromic acid, hydriodic acid, acetic acid, propionic acid, sulfuric acid, phosphoric acid or hydroboric acid, is added. In the case of neutral hydrophilic monomers, such as dimethylacrylamide or vinylpyrrolidone, the solution obtained in 1 is left unchanged.
