THE PRESENT INVENTION CONCERNS AN ESTER CONTAINING NITROGEN OF AN INTERPOLYMER CONTAINING CARBOXY, THEIT INTERPOLYMER HAVING A SPECIFIC VISCOSITY REDUCED FROM APPROXIMATELY 0.005 TO ABOUT 1 AND COMING FROM AT LEAST 2MONOMERS, ONE OF SAID MONOMERES IS ALIPHATIC A LOW MOLECULAR WEIGHT OR STYRENE AND THE OTHER OF SAID MONOMERES BEING AN ALIPHATIC ACID ALPHA, BETA-INSATURE, ONE OF ITS ANHYDRIDES OR ESTERS, IT IS CONTAINING NITROGEN BEING PRACTICALLY LACK OF CHARACTERIZED AND PRESENT ACIDITY. IN ITS POLYMERIC STRUCTURE OF EACH OF THE FOLLOWING GROUPS THAT ARE DERIVED FROM THE CARBOXY DUDIT INTERPOLYMER GROUPS: A.A CARBOXYL ESTER GROUP, THREE CARBOXYL ESTER GROUP WITH AT LEAST 8ATOMS OF ALIPHATIC CARBON AND CARBOXY DUDIT INTERPOLYMER GROUPS: A.A CARBOXYL ESTER GROUP, THREE CARBOXYL ESTER GROUP HAVING AT LEAST 8ATOMS OF ALIPHATIC CARBON AND CARBON DIDIT IN THE RADICAL-ESTER GROUP, B. OF A POLYAMINO COMPOUND HAVING A PRIMARY OR SECONDARY AMINO GROUP AND AT LEAST ONE MONOFUNCTIONAL AMINO GROUP, OR THE MOLAR RATIO OF THE CARBOXY GROUPS DEDICATED ESTERIFIED INTERPOLYMER TO PROVIDE A TO CARBOXY GROUPS DUDIT NEUTRALIZED INTERPOLYMER TO PROVIDE B IS IN A RANGE OF ABOUT 85:15 TO ABOUT 99: 1. THESE COMPOUNDS ARE USEFUL AS ADDITIVES FOR LUBRICANTS. |
