Abstract
Abstract Nitrogenous condensation products and hydrolysis products thereof are provided wherein the condensate of a fatty acid and diamine is reacted with an unsaturated dicarboxylic acid or a partial ester thereof; optionally the product of such a reaction or a similar product obtained from an unsaturated monocarboxylic acid is further reacted with a halocarboxylic acid. The unhydrolyzed products can be formulated as imidazolines.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
A nitrogenous compound of the formula ##STR22## wherein R 3 CO 2 M is the residue of a monocarboxylic acid of 2 to 5 carbon atoms; n is 0 to 4; y is 0 or 1; m is from 0 to 2; M is selected from the group consisting of hydrogen and a cation; Ac is a saturated residue of an α,β-unsaturated dicarboxylic acid of 4 or 5 carbon atoms wherein the carboxylic acid groups are on adjacent carbon atoms and the double bond is between the two carbon atoms or immediately adjacent to one of them and wherein one of the carboxylic acid groups may be neutralized with a base or esterified with an alcohol of 1-6 carbon atoms R is an alkyl of alkenyl group of 5-25 carbon atoms and each R 1 is alkylene of 2-4 carbons and may be the same or different.
Claim 2
Dependent Claim
147 words
