Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) 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. [1] Physicochemical properties [ edit]

Theoretical studies of hydrolysis and stability of polyacrylamide polymers

Water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers are among the most commonly used chemicals in oilfield applications. In polymer-augmented water-flooding Enhanced Oil Recovery (EOR) processes, HPAM polymers are often used as mobility-control agents to increase the viscosity of stimulation fluids in order to improve the sweep efficiency [1] , [2] , [3] .
