Process for improving shelf stability of liquid overbased calcium carboxylates, mixed metal stabilizers containing same, and stabilizing halogen-containing polymers therewith |
摘要 |
Shelf stable liquid overbased calcium carboxylates are prepared by reacting a calcium base with a monocarboxylic acid, and carbonating in the presence of a promoter mixture with a phenol and an alcohol under controlled temperature conditions, to produce shelf stable liquids. Mixed metal stabilizer compositions are prepared by blending the stable liquid calcium carboxylate with a metal carboxylate of zinc, cadmium or tin. The mixed metal carboxylates are also shelf stable and are used for stabilizing halogen-containing polymers to provide heat stability, clarity and improved plate out properties.
