Abstract: A series of itaconic acid homopolymers (PIA) were synthesized by free radical polymerization in aqueous solution, using itaconic acid as monomer and initiator at different reaction temperature. The prepared PIAs were characterized by IR, gel permeation chromatography (GPC) and iodometry, and their anti-scale and corrosion-inhibition performance were evaluated. The results showed that the PIA with average molecular weight of 1 800-2 700 had excellent performance ,the anti-scale rate for CaCO3 was more than 65%, and the corrosion-inhibition rate for carbon steel was more than 90% .

Key words: itaconic acid, homopolymer, anti-scale, corrosion-inhibition
