  The compounds are esters and amides of trialkylhydroxyphenylalkanoic acid having the formula ##SPC1## Wherein R, R.sup.1 and R.sup.2 are independently lower alkyl or cycloalkyl groups, R.sup.3 is hydrogen, alkyl, cycloalkyl, alkylene, phenyl, phenyl substituted by alkyl groups, alkylthioethyl, thiobis-alkylene, alkyleneoxyalkylene, polyoxyalkylene or a polyvalent cyclic or acyclic hydrocarbon radical, R.sup.4 is hydrogen, lower alkyl, cycloalkyl, R.sup.5 is hydrogen, alkyl, phenyl, phenyl substituted with alkyl groups, alkylene, polyoxyalkylene or polyvalent cyclic or acyclic hydrocarbon radical, A is lower alkylene, m is 1 to 4 and n is 1 to 6. The ester compounds of this invention are prepared via usual esterification procedures from a suitable alcohol and an acid of the formula I ##SPC2## or an acid halide or acid anhydride thereof. The higher alkyl esters can also be prepared from the lower alkyl ester, especially the methyl ester of the above represented compounds, by transesterification with a higher alkanol. The amide compounds of this invention are prepared by usual amidation procedures by reacting a carboxylic acid of formula I or an acid chloride or anhydride or a lower alkyl ester thereof with the appropriate amine. The compounds are useful as stabilizers for organic materials, especially polyolefins, which deteriorate upon exposure to light and heat.

  这些化合物是三烷基羟基苯基丙酸酯和酰胺，其化学式为##SPC1##其中R、R.sup.1和R.sup.2分别是低烷基或环烷基，R.sup.3是氢、烷基、环烷基、烷基烯、苯基、被烷基取代的苯基、烷基硫乙基、硫代双烷基、烷氧基烷基、聚氧烷基或多价环烷基或非环烷基碳氢基，R.sup.4是氢、低烷基、环烷基，R.sup.5是氢、烷基、苯基、被烷基取代的苯基、烷基烯、聚氧烷基或多价环烷基或非环烷基碳氢基，A是低烷基烯，m为1至4，n为1至6。本发明的酯化合物通过适当的醇和化学式I的酸或其酸卤或酸酐进行通常的酯化反应制备而成。高烷基酯也可以通过用高碳醇对低烷基酯，特别是上述化合物的甲酯进行酯交换反应制备而成。本发明的酰胺化合物通过通常的酰胺化反应，通过反应化学式I的羧酸或其酸氯或酐或其低烷基酯与适当的胺反应制备而成。这些化合物可用作有机材料的稳定剂，特别是聚烯烃，因其暴露于光和热会恶化。
