    摘要: Metal materials in contact with aqueous systems are prevented from corrosion by a method which comprises adding a copolymer having a molecular weight in the range of 1,000 to 20,000 and formed between isobutylene and at least one member selected from among maleic acid, water-soluble salts thereof, and maleic anhydride to water of such quality that the Langelier index thereof is not less than 1.5 and the relation,(SiO.sub.2).times.(CaH).gtoreq.2,000(wherein (SiO.sub.2) stands for the SiO.sub.2 concentration in the water (mg/liter) and (CaH) for the calcium hardness (mg/liter as CaCO.sub.3 in the water).
