    • Disclosed is a solution that comprises (A) a solvent; (B) about 0.001 to about 20 wt % of a terpolymer that comprises the condensation reaction product of (1) an aromatic compound that contains a benzene or naphthalene ring substituted with the group OR or SR, where R is hydrogen, alkyl from C1 to C15, or aryl, alkaryl, or aralkyl from C6 to C15; (2) about 0.1 to about 10 moles of a carbonyl compound per mole of said aromatic compound; and (3) about 0.1 to about 10 moles of a thiourea per mole of said aromatic compound (C) about 1 to about 5 wt % of a base; (D) about 0.1 wt % to saturation of a salt; and (E) 0 to about 20 wt % of an alcohol. Also disclosed is a method of making the terpolymer in the absence of an acid catalyst and a method of inhibiting the formation of scale on reactor components in contact with polymerizing vinyl chloride monomer.
