PROCESS FOR PREPARING LIQUID OVERBASED METAL CARBOXYLATES MIXED METAL STABILIZERS CONTAINING SAME AND STABILIZED HALOGEN-CONTAINING POLYMERS THEREWITH

摘要

Liquid overbased alkaline or alkaline earth metal carboxylates, in particular barium carboxylates, are prepared by methods which involve the use of beta-diketones as reaction promoters during carbonation. Mixed metal stabilizers containing an overbased metal carboxylate salt are used as stabilizers for halogen containing polymers, such as polyvinyl chloride (PVC).
