Patent ID: 8017805

Claim:
An isomeric mixture comprising diaromatic amine compounds of the general formula: wherein n is from 0 to 3; m is from 0 to 3; each R and R 3 substituent is independently hydrogen, a straight or branched C 1 -C 32 alkyl group or alkenyl group, substituted or unsubstituted C 3 -C 12 cycloalkyl, substituted or unsubstituted C 5 -C 12 aryl, hydroxyl-containing group, halogen, substituted or unsubstituted C 1 -C 20 alkoxy, ester-containing group, ether-containing group, polyether-containing group, amide-containing group, or amine-containing group or two R substituents and/or two R 3 substituents together with the carbon atom to which they are bonded are joined together to form a substituted or unsubstituted, saturated, partially saturated or unsaturated C 5 -C 30 ring structure optionally containing one or more heteroatoms; R 1 and R 2 together with the carbon atom to which they are bonded are joined together to form a substituted or unsubstituted, saturated or partially saturated C 5 -C 30 ring structure optionally containing one or more heteroatoms, and R 4 and R 5 together with the carbon atom to which they are bonded are joined together to form a substituted or unsubstituted, saturated or partially saturated C 5 -C 30 ring structure optionally containing one or more heteroatoms.
