ABSTRACT:
Diacids having the formulae ##STR1## wherein the radicals R, which can be the same or different, are alkylene radicals having 1 to 16 carbon atoms per radical, R' is an alkylene radical --C.sub.n H.sub.2n --, n being an integer from 0 to 15, with the further provision that there are at least 6 carbon atoms in the chain separating the two carboxyl groups --COOH, R" is hydrogen or an alkyl radical having 1 to 6 carbon atoms per molecule; X is selected from the group of phenylene, naphthylene, cyclohexylene and decahydronaphthylene, Q is selected from the group of radicals consisting of hydrogen, halogen, alkyl, dialkylamino, alkoxide, hydroxy, alkylthio, and mercapto, which are useful precursors for diesters, polyamides and polyesters. The diesters are valuable plasticizers for PVC and the polyamides not having a crystalline melting point can be spun into fibers, which in turn can be used in the textile industry for making fabrics. Also disclosed are procedures to make the novel compounds.
