wherein p is 3 or greater;
wherein each n is independently selected from integers equal to 2 or greater;
wherein R1 is a C3-C20 aliphatic hydrocarbon group of valence p which is branched or linear and which is substituted or unsubstituted;
wherein each R2 is independently selected from C2-C20 divalent aliphatic or aromatic hydrocarbon groups which are branched or linear and which are substituted or unsubstituted; and
wherein each Q is independently selected from —NH2 or a moiety according to formula II:

OG Complex Work Unit Chemistry
wherein each R3 is independently selected from C8-C60 alkenyl groups which are substituted or unsubstituted,
providing that at least one Q is the moiety according to formula II.
