Abstract
The invention comprises polyglycol esters of the formula <FORM:0728643/IV (a)/1> in which R is preferably unsubstituted phenyl, R1 is phenyl, preferably unsubstituted, or cycloaliphatic of 5-7 C atoms, R11 is H or OH, or R1 and R11 together are an alkylene chain of 4-6 C atoms; R111 is H or a hydrocarbon radical of at most 6 carbon atoms, and n is 4-50; and the method of preparing such esters. In examples, such polyglycol esters of diphenyl acetic, phenyl cyclopentyl acetic and phenyl cyclohexyl acetic acids are described, the polyglycol monomethyl ethers used being of average molecular weights 350 and 500; a -a -diphenyl-a -hydroxy acetic acid is also specified.ALSO:The invention comprises polyglycol esters of the formula <FORM:0728643/IV (b)/1> in which R is preferably unsubstituted phenyl, R1 is phenyl, preferably unsubstituted, or cycloalphatic of 5-7 C atoms, R11 is H or OH, or R1 and R11 together form an alkylene group of 4-6 C atoms; R111 is H or a hydrocarbon radical of at most 6 carbon atoms, and n is 4-50; and the method of preparing such esters by esterification of the corresponding acids. In examples the polyethylene glycol monomethyl ether is used to esterify diphenylacetyl chloride, and phenyl cyclopentane-1-carboxylic chloride, the polyglycol used having average molecular weights respectively of 500 and 350, to give products having a similar range of molecular weights. Phenyl cyclohexyl acetyl chloride may be similarly esterified, and a -a -diphenyl-a -hydroxy acetic acid is also specified.
