Summary:1. Field of the Invention The present invention provides a process for preparing an overbased barium complex and an overbased barium complex prepared thereby. The process includes the steps of: heating a mixture of barium hydroxide monohydrate and an isomeric mixture of from about Cto about Calcohols in the presence of a solvent, thereby producing a first mixture; contacting the first mixture and an isomeric mixture of from about Cto about Cbranched carboxylic acids, thereby producing a second mixture which includes unreacted barium hydroxide; and contacting the second mixture and carbon dioxide, thereby producing the overbased barium complex. The overbased barium complex of the present invention is useful in the stabilization of halogen-containing polymers.
