Abstract

The invention comprises compounds of formula <FORM:0970969/C1/1> wherein R1 and R2 are H, alkyl or aryl and R3 is alkyl or aryl, or both R2 and R3 may be part of a carbocyclic ring; Ar has the formula <FORM:0970969/C1/2> wherein the substituents R4 - - - R7 and R10 - - - R13 are H, halogen, alkyl or aryl, R8 and R9 are H, alkyl or aryl. Compounds of the first formula, wherein R1 is H, R2 and R3 are as above defined and Ar is arylene, are made by reacting a dihydroxy-arene with NaOH or KOH and a halo-alcohol containing the structural unit >C(OH)CX3, X being Cl, Br or I and neutralizing the product; a ketone plus a halo-form may be used as an alternative to the halo-alcohol. The examples describe the reaction of chloroform, NaOH and 2,2-bis(4-hydroxyphenyl) propane to give 2,2-bis [4-carboxy-1-methyl-ethoxy)phenyl] propane and the conversion of this dicarboxylic acid to its dimethyl ester.ALSO:Polyesters may be prepared by reacting with glycol a compound of formula <FORM:0970969/C3/1> wherein R1 is H or lower alkyl e.g. methyl, R3 is alkyl or aryl and R2, R8 and R9 are H, alkyl or aryl, or R2 and R3 are part of a carboxylic ring; the benzene rings in the formula may be substituted with halogen, alkyl or aryl groups.
