Aim:(a) To polymerize acrylamide (monomer) in water to polyacrylamide (polymer) by free radical polymerization using a "redox" pair of initiators. (b) To follow the kinetics of polymerization by monitoring the variation of temperature and viscosity (measured by using Stokes Law for falling spheres) with time. Materials and Apparatus:

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and cell fragments; therefore, one of its

Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water.

The polyacrylamide is a synthetic cationic polymerization flocculants and polymer flocculant powder. It is mainly related to chain length and the charge of the dewatering performance of polyacrylamide excessive dosage. The positive charge on the ion polyacrylamide adsorption, due to electrostatic repulsion, it will reduce the sludge settling
