Claims
- 1. A composition of matter obtained by reacting, at 230.degree.-250.degree. C., two moles modified polyamine with one mole of a member of the group consisting of polycarboxylic acids and anhydrides of the following general formulae: ##STR8## wherein x and y are integers from 3 to 9, x and y together equal 10-14, at least one Z is a carboxylic acid group and any remaining Z is hydrogen, and wherein the modified polyamine is formed by a Michael addition reaction of a polyalkylene amine with a 1,2-unsaturated acid able to undergo Michael addition of the amines across the double bonds producing amino acids which can undergo polymerization to low and high molecular weight amino polyamides.
- 2. The composition of claim 1 obtained by co-reacting the member with kraft lignin, desulfonated lignosulfonates, or dimerized fatty acids prior to their reaction with the modified polyamines.
