摘要:
Halogen-containing polymers are heat-stabilized by physiologically unobjectionable mixtures consisting of 10 to 70% by weight of an aluminum salt, 10 to 80% by weight of a calcium salt and 10 to 70% by weight of a zinc salt of an aliphatic mono- or dicarboxylic acid or an aromatic mono-, di-, or tricarboxylic acid.
