Dithiodialkanoic acid esters and polymers stabilized therewith |
摘要 |
Multifunctional dithiodialkanoic acid esters useful in the stabilization of organic materials normally susceptible to oxidative degradation are prepared by contacting a selected dithiodialkanoic acid chloride with a selected 4-(3-hydroxypropyl)(mono- or di-alkyl) phenol under ester-forming reaction conditions. In a preferred embodiment, the ester is bis-3-(3',5'-di-t-butyl-4'-hydroxyphenyl)propyl dithiodipropionate.
