Reaction product of an aliphatic olefinpolymer-succinic acid producing compound with an amine and reacting the resulting product with a boron compound

Claim 1

A PROCESS FOR PREPARING OIL-SOLUBLE NITROGEN AND BORON-CONTAINING COMPOSITIONS COMPRISING FORMING AN ACYLATED NITROGEN INTERMEDIATE BY THE REACTION AT A TEMPERATURE WITHIN THE RANGE OF FROM ABOUT 80*F TO ABOUT 250*F C., OF A SUBSTANTIALLY ALIPHATIC OLEFIN POLYMER-SUBSITUTED SUCCINIC ACID-PRODUCING COMPOUND HAVING AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS IN THE POLYMER SUBSTITUENT WITH AT LEAST ABOUT ONE-HALF EQUIVALENT OF AN AMINE, FOR EACH EQUIVALENT OF THE ACID-PRODUCING COMPOUND USED, SELECTED FROM THE CLASS CONSISTING OF ALKYLENE AMINES AND HYRODXY-SUBSTITUTED ALKYLENE AMINES, AND REACTING, AT A TEMPERATURE BETWEEN ABOUT 50*F C. AND ABOUT 250*F C., SAID ACYLATED NITROGEN INTERMEDIATE WITH A BORON COMPOUND SELECTED FROM THE CLASS CONSISTING OF BORON OXIDE, BORON HAIDE, BORON ACIDS, AND ESTERS OF BORON ACIDS IN AN AMOUNT TO PROVIDE ROM ABOUT 0.1 ATOMIC PROPORTION OF BORON FOR EACH MOLE OF SAID ACYLATED NITROGEN INTERMEDIATE TO ABOUT 10 ATOMIC PROPORTIONS OF BORON FOR EACH ATOMIC PROPORTION OF NITROGEN OF SAID ACYLATED NITROGEN INTERMEDIATE.
