| description | Disclosed is a composition of matter which provides heat and color stability to polyvinyl chloride resins, especially of the flexible type, said composition consists essentially of (A) about 10 to about 40 parts by weight of a zinc carboxylate; (B) about 50 to about 80 parts by weight of an alkyl ester of thiodipropionic acid; and (C) about 5 to about 20 parts by weight of a phenolic antioxidant. A PVC resin containing the above composition of matter is also disclosed.
L'invention porte sur une composition qui donne aux résines de poly(chlorure de vinyle), notamment à celles de type flexible, une bonne résistance à la chaleur et à l'altération des couleurs. La composition est principalement constituée d'environ : A) 10 à 40 parties en poids d'un carboxylate de zinc; B) 50 à 80 parties en poids d'un ester alkylique d'acide thiodipropionique; C) 5 à 20 parties d'un antioxydant phénolique. L'invention présente également une résine de PVC renfermant la composition ci-dessus. |
