摘要：
Maleic anhydride homopolymer corrosion inhibitors, maleic acid homopolymer corrosion inhibitors, methods for preparing the same, and methods of inhibiting corrosion are provided. The corrosion inhibitors may exclude phosphorus and may contain a hydrolysate of a maleic anhydride homopolymer or a hydrolysate of a maleic acid homopolymer. The maleic acid homopolymer may include from about 2 to about 5 maleic acid repeating units and the maleic anhydride homopolymer may include from about 2 to about 5 maleic anhydride repeating units.
