The oligomer is prepared in water solvent by adding maleic acid anhydride, phosphinic acid or its salt to the reaction water solution according to a certain molecular ratio, and dropping in some primer.The corrosion under film has been found.In order to overcome the disadvantage, a series of studies have been carried through.Phosphorus acid is added,so as to make it phosphonated.The newoligomer has high density branched chain of phosphonic acid functional groups.This product has undergone tests such as scale inhibition, pre-filming,corrosion inhibition.The results show that it can be used as scale inhibitor and corrosion inhibitor in water treatment.
Key words: phosphonic acid; oligomer; scale and corrosion inhibitors
