MIXTURES OF 3-(3,5-DIALKYL-4-HYDROXYPHENYL)-PROPIONIC ACID ESTERS OF ALKANEDIOLS
Mixtures of 3-(3,5-dialkyl-4-hydroxyphenyl)-propionic acid esters are stabilizers of organic material against thermo-oxidative ageing. They are prepared by conventional esterification techniques. A typical embodiment is a mixture of 2,2,4-trimethyl-1,6-hexanediol bis[ 3-(3,5-di-t-butyl-4-hydroxyphen...

Zusammenfassung: | Mixtures of 3-(3,5-dialkyl-4-hydroxyphenyl)-propionic acid esters are stabilizers of organic material against thermo-oxidative ageing. They are prepared by conventional esterification techniques. A typical embodiment is a mixture of 2,2,4-trimethyl-1,6-hexanediol bis[ 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate] and 2,4,4-trimethyl-1,6-hexanediol bis[ 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate]. |
