Process for preparing liquid overbased metal carboxylates, mixed metal stabilizers containing same, and stabilized halogen-containing polymers therewith

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).
