Abstract

PURPOSE:To obtain a nonpolluting and safe anticorrosive for a metal maintaining stably a significant corrosion preventing effect over a long period when added by a small amt., by using a copolymer of (meth)acrylic acid (salt) with methallylsulfonic acid (salt) as an effective component. CONSTITUTION:(Meth)acrylic acid and/or a salt thereof (A) is copolymerized with methallylsulfonic acid and/or a salt thereof (B) in 95/5-40/60 molar ratio of A/B in the presence of a polymn. initiator in a solvent such as water or lower alcohol at 30-100 deg.C to obtain a copolymer having 500-25,000 weight averoge mol.wt. An aq. soln. of the copolymer having 5-60wt.% concn. is added to a system to be protected from corrosion so that the copolymer is contained by 5-200mg/l. The aq. soln. is used as an anticorrosive for a metal.
