    摘要: Novel oligomeric quinolinium salts are disclosed. These are formed by reacting quinoline oligomers with alkylating agents such as benzyl halide, p-.alpha.-xylenyl dihalide and alkyl sulfates. The novel oligomeric quinolinium salts are useful as metal corrosion inhibitors, and especially as aqueous acid corrosion inhibitors. The novel compounds are represented by the formulae: ##STR1## wherein n and m are integers, with n being greater than 2 and up to about 200 and m being equal to or greater than 1, R is H or an alkyl group having from 1 to about 20 carbon atoms, R.sup.1 is an alkyl group having 1 to about 20 carbon atoms, X.sup.- is a chloride, bromide or iodide and Z.sup.- is an anion selected from BF.sub.4.sup.-, SO.sub.4.sup.=, ClO.sub.4.sup.-, PF.sub.6.sup.- and HSO.sub.4.sup.-.
