Abstract: Disclosed is a process for neutralizing an inorganic acid in the presence of a halogenated aliphatic polybasic acid or anhydride. The neutralization is carried out by adding to said acid or anhydride a primary or secondary amine containing at least two active hydrogen atoms per molecule as determined by the Zerewittenoff Method, and neutralizing the inorganic acid in the presence of the polybasic acid or anhydride. In one embodiment, the halogenated aliphatic or alicyclic polybasic acid or anhydride is present in a mixture wth a halogenated aromatic polybasic acid or anhydride and with a polyol and the neutralization is carried out before substantial polymerization occurs between the acids and polyol.
