Polyaspartic acid graft copolymers containing different proportion hydroxyl have been synthesized from polysuccinimide and 2-aminoethanol. The corrosion inhibition capacity and biodegradability of the graft copolymers are studied by rotation specimen weight-losing method and shaking-bottle incubating test. The results show that the corrosion inhibition capacity of the polyaspartic acid graft copolymers containing hydroxyl gets higher with the increasing proportion of hydroxyl,but the biodegradability is reduced.
Key words： polyaspartic acid; corrosion inhibition; graft copolymer
