Conventional free radical techniques are applicable and conunonly solution polymerization is carried out, using water as the solvent. In a typical process a water-soluble initiator such as potassium persulphate is added to an aqueous solution of the acid together with an activator, e.g., sodium thiosulphate, and a transfer agent, e.g., mercaptosuccinic acid a reaction temperature of 50 100°C is used. Alternatively, if solid polymer is required, it is convenient to conduct the polymerization in a solvent such as benzene in which the polymer is insoluble in this case benzoyl peroxide is a suitable initiator. Salts of acrylic and methacrylic acids may also be polymerized in aqueous solution by treatment with free radical initiators. In addition to the polymerization of the appropriate monomer, the hydrolysis of a suitable polymer represents a further method of preparation of polymeric acids and salts.
