Abstract:
p-Alkyl or cycloalkyl phenoxy alkanols and esters are provided having the structure: ##STR1## in which: R. sub. 1 is an alkyl group having from one to six carbon atoms, preferably tertiary, and still more preferably tertiary-butyl; or a bivalent cycloalkylene group condensed with the phenyl group at adjacent ring carbons thereof, such as in indane; R. sub. 2 is lower alkyl having from one to three carbon atoms or hydrogen; R. sub. 3 is hydroxyl or an ester group selected from the group consisting of COOR. sub. 4 and OOCR. sub. 4 derived from unsubstituted and hydroxy-substituted monocarboxylic acids and COOR. sub. 5 OOC and OOCR. sub. 5 COO derived from unsubstituted and hydroxy-substituted dicarboxylic acids, the acids being selected from the group consisting of aliphatic acids, including carbamic acid, having from one to about twelve carbon atoms; cycloaliphatic acids having from three to about twelve carbon atoms; carbocyclic aromatic acids having from six to about twenty carbon atoms; and nitrogen heterocyclic aromatic acids having from five to about twelve carbon atoms, R. sub. 4 being monovalent aliphatic, cycloaliphatic, aromatic, or nitrogen heterocyclic aromatic, and R. sub. 5 being divalent aliphatic, cycloaliphatic, aromatic, or nitrogen heterocyclic aromatic, the acids being esterified with aliphatic alcohols having from one to six carbon atoms; and carbonic acid monoalkyl esters, the alkyl having from one to three carbon atoms; and n. sub. 1, n. sub. 2 and n. sub.
