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: 6
Claim 1
Independent Claim
86 words
A nitrogenous compound of formula: ##STR22## wherein Y is a saturated residue of an α, β-unsaturated dicarboxylic acid of 4 or 5 carbon atoms wherein the carboxylic acid groups are an 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 and R is an alkyl or alkenyl group of 5-25 carbon atoms.
Claim 2
Dependent Claim
