Abstract

Block polyamido polyamine condensation products of an aromatic polycarboxylic acid component with a polyoxyalkylene polyamine component prepared by reacting the polycarboxylic acid component with an amount of the polyoxyalkylene polyamine component sufficient to react each carboxyl group with 1 mole of the polyoxyalkylene polyamine component.

The polyoxyalkylene polyamine being selected from the group consisting of polyoxypropylene diamines, polyoxyethylene diamines, polyoxyethylene/oxypropylene diamines and polyoxypropylene triamines, and the aromatic polycarboxylic acid component being selected from the group consisting of C₈ to C₂₈ benzene dicarboxylic acids, benzene tricarboxylic acids, naphthalene carboxylates, hemimellitic acid, 1,1,3-trimethyl-3-phenylindan-4'"'"',5-dicarboxylic acid, trimellitic acid, and anhydrides and C₁ to C₄ alkyl esters thereof.

Claims

1. A method of preparing a block polyamido polyamine condensation product, said block polyamido polyamine condensation product being the condensation product of isophthalic acid with bis-aminoethyl ether, said method comprising the steps of:

(a) reacting said isophthalic acid,

(b) with about 1.05 to about 1.2 moles of said bisaminoethyl ether per mol of isophthalic acid,

(c) said isophthalic acid being reacted with said bis-aminoethyl ether in an amount sufficient to react each carboxyl group of said isophthalic acid with 1 mol of said bis-aminoethyl ether under reaction conditions including a temperature within the range of about 150°

to about 250°

C., a pressure of about 40 mm to about 3,000 psig and a reaction time of about 0.5 to about 12 hours, sufficient to form said block amidoamine reaction product, said amidoamine reaction product having terminal groups consisting essentially of primary amine groups,

(d) the amidoamine being a water soluble, methanol soluble solid having a melting point of about 80°

C.
