Abstract
PURPOSE: A white stabilizer composition, having improved antioxidant property and preventing effect on copper discoloration and corrosion without coloration by heat and change with time, and containing 4,4-thiobis(3-methyl-6-tert-butylphenol) and a specific amount of a chain polyfunctional carboxylic acid.
CONSTITUTION: A stabilizer composition prepared by incorporating (A) 4,4'- thiobis(3-methyl-6-tert-butylphenol) with (B) 0.0001W1.0wt%, preferably 0.001W 0.1wt%, chain polyfunctional carboxylic acid. An alkali metallic salt or ammonium salt of oxalic acid, tartaric acid, etc. may be preferred as the component (B), and trisodium citrate is most preferred.
