- wherein Ar is an aromatic hydrocarbyl nucleus of 6 to about 20 carbon atoms, each R is as defined hereinabove, and Y is 2 to about 8.
- 6. A composition as claimed in claim 5 wherein the subtituent is an aliphatic substituent of about 12 to about 250 carbon atoms.
- 7. A composition as claimed in claim 6 wherein the substituent is a purely aliphatic substituent of about 30 to about 250 carbom atoms.
- 8. A composition as claimed in claim 6 wherein the amino compound is (1) a polyalkylene polyamine.
- 9. A composition as claimed in claim 7 wherein the amino compound is (1) a polyalkylene polyamine.
- 10. A composition as claimed in claim 7 wherein the amino compound is (3) an aromatic polyamine.
- 11. A composition as claimed in claim 4 wherein the amino compound is primary or secondary mono-amine having hydrocarbon-based substituents of 1 to about 30 carbon atoms.
- 12. A composition as claimed in claim 11 wherein the Mannich condensation product is made from a phenol bearing a hydrocarbon-based substituent of about 6 to about 400 carbon atoms and formaldehyde or a formaldehyde precursor.
- 13. A composition as claimed in claim 12 wherein the phenol's substituent is an aliphatic substituent of about 30 to about 250 carbon atoms.
- 14. A concentrate as claimed in claim 3 wherein said nitrogen-containing Mannich condensation product is made from a phenol bearing a hydrocarbon-based substituent of about 6 to about 400 carbon atoms, formaldehyde, or a formaldehyde precursor and an amino compound selected from the group consisting of (1) polyalkylene polyamines of the general formula ##STR8## wherein each R is independently a hydrogen atom or a C.sub.1-12 hydrocarbon-based group with the proviso that at least one R is a hydrogen atom, n is 1 to 10 and "alkylene" is a C.sub.1-10 alkylene group, (2) heterocyclic-substituted polyamines of the formula ##STR9## wherein R and alkylene are as defined hereinabove, m is 0 to 10, and Y is an oxygen or divalent sulfur atom or --N--R* and R* is either a R or a ##STR10## group and (3) aromatic polyamines of the general formula
