摘要
Liquid overbased alkali or alkaline earth metal carboxylates, particularly barium carboxylates, are prepared by a process which includes the use of a beta diketone as a reaction promoter during carbonation. Mixed metal stabilizers containing the overbased metal carboxylates are used as stabilizers for halogen-containing polymers such as polyvinyl chloride (PVC).
