ABSTRACT:
Stabilizers for chlorine-containing resins, derived from pentaerythritol and/or polypentaerythritols, which comprises at least one member selected from (1), a dehydration condensation product of pentaerythritol or polypentaerythritol, (2) a partial esterification product of pentaerythritol, polypentaerythritol or the dehydration condensation product with an aliphatic polybasic acid, (3) a partial esterification product of polypentaerythritol or the dehydration condensation product with an aromatic mono- or poly-basic acid, and (4) a partial esterification product of pentaerythritol, polypentaerythritol or the dehydration condensation product with an aliphatic or aromatic polybasic acid and a higher fatty acid. The stabilizers have the excellent effect of stabilizing chlorine-containing resins, and particularly the combination use with known organic zinc salt stabilizers brings excellent results.
