摘要

esters of 3 tert - butyl - or 3 tert - butyl - 4 - 5 - alkyl - hydroxyphenyl (alkan) - carboxylic acids of the formula i $f1 with oxethylaten of monofunktionellen phenols or cycloaliphatic or aromatenhaltigen monofunktionellen alcohols of formulas ii to v $f2 with n and1 = 1 to 3), preferably 1, p = 0 to 7, preferably 1, 3 and 7, r = h, c1 to c4 alkyl, aryl, preferably h, r3, r4, r5 = h, c1 to c4 alkyl, aryl, c5 to c12 - cycloalkyl, halogen (in the formulas ii to iv), preferably h or c1 to c4 alkyl. to manufacture this ester esterified to three tertiary butyl or 3 tert - butyl - 5 - alkyl - 4 - hydroxy phenyl - (alkan) carboxylic acid; orwith the oxethylaten derivatives of phenols or alcohols, or in the presence of estert to known catalysts. the esters can be used for the stabilization of polymers.
