Beschreibung
Zusammenfassung:	Esters of 3-hydroxy-2,2-dimethylpropyl 3-hydroxy-2,2-dimethylpropionate with 3,5-dialkyl-4-hydroxyphenylalkanoic acids are stabilizers of organic material. The compounds of which 3-hydroxy-2,2-dimethylpropyl-(3-hydroxy-2,2-dimethylpropionate)-bis[3, -(3',5',-di-t-butyl-4'-hydroxyphenyl)propionate] is a typical embodiment, are prepared through esterification of 3-hydroxy-2,2-dimethylpropyl-3-hydroxy-2,2-dimethylpropionate.
