Problems solved by technology

The development of such compositions is thus expensive and time-consuming, with the developer attempting to identify and combine cooperative components in the correct amounts and concentrations to achieve a useful composition that has characteristics is as close to a specified list as possible.
Formulation of such compositions, requiring multiple different components to achieve different end goals when in combination is both challenging and costly.

embodiments

[0190]In addition to the embodiments described above, in the examples and in the claims, other embodiments described herein include the following:

[0191]In one embodiment, a composition comprises a polyamidopolyamine produced by the reaction of a polybasic acid and primary polyamine, which is linear, cyclic, branched or cross-linked, said polyamidopolyamine having a molecular weight of about 500 to about 100,000 and having one or more repeating pendant amino groups, wherein said polyamidopolyamine is of the Formula A wherein each polybasic acid is a dimer acid; each primary polyamine is independently a diamine, a triamine, or a tetraamine or an amine comprising 5 or more free amino groups; a and a′ are independently 1 or 2; b is 0, 1 or 2; and r is a number between 2 to about 10, including both endpoints of the range. In another embodiment, this composition is formed by the reaction having a 2:1 mole ratio of polyamine to dimer acid.

[0192]In another embodiment, the composition furthe...

Antimicrobial Activity of Polyamidopolyamine Composition 3533-171

[0226]The results of this experiment are shown in FIG. 1.

[0227]A polyamidopolyamine composition of Formula A, referred to as 3533-171, was produced by a condensation reaction of 2 moles of the Jeffamine® T403 polyetheramine (Huntsman Corporation) polyamine and 1 mole of adipic acid. The T403 amine is a trifunctional primary amine having an average molecular weight of approximately 440 with its amine groups located on secondary carbon atoms at the ends of aliphatic polyether chains.

[0228]The reaction was conducted at 160-165° C., with water as a diluent added at the end of the reaction. The final composition contained greater than about 73% of the polyamidopolyamine, up to 15% by weight of free T-403 polyamine and about 12.8% water. The composition has a cloud point (inverse solubility) at about 31° C. (88° F.).

[0229]The composition was diluted to 0.75% in water and was measured for the time in seconds that foam collaps...

Antimicrobial Activity of Polyamidopolyamine Composition 3587-17

[0231]The results of this experiment are shown in FIG. 2.

[0232]A polyamidopolyamine composition of Formula A, referred to as 3587-17, was produced by a condensation reaction of 2 moles of T403 polyamine (Huntsman) with 1 mole of azelaic acid, with triethanolamine (TEA) as a solvent. The reaction was conducted at 160-165° C. The final composition contained about 46% by weight of the polyamidopolyamine, up to 9.4% by weight of free T-403 polyamine and about 45% by weight triethanolamine. The composition has a cloud point (inverse solubility) at about 24° C. (75° F.).

[0233]The composition 3587-17, diluted to 0.75% in water was measured for the time in seconds that foam collapses to zero foam. The decay was less than 15 seconds.

[0234]The polyamidopolyamine-containing composition 3587-17 was evaluated for anti-microbial ability in the following assay. The pH for the composition was adjusted to approximately 9.3. The composit...

Abstract

Compositions comprising a polyamidopolyamine and / or a non-poly-meric amidoamine are disclosed for imparting multiple desired characteristics to a variety of industrial compositions. In certain embodiments, these compositions are prepared by condensing a C4 to C16 poly basic acid, monobasic acid or derivative thereof with a polyamine comprising a primary amino group, and in the presence of an optional organic diluent. Certain specific polyamidopolyamine and a non-polymeric amidoamine formulae and compositions containing same are disclosed, as are methods of use of these compositions.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of the priority of US Provisional Patent Application No. 62 / 147,840, filed Apr. 15, 2015, which application is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Various compositions for industrial use require specific characteristics for use, e.g., paint requires a certain amount of rheology control and coating ability, as well as a specified amount of bioresistance. Analogously metal working fluids require lubricity, load carrying ability, the control of foaming during use and microorganism growth control. Still other compositions abound that have specific and varied requires for anti-foaming or defoaming during use, and also bioresistance, etc. Generally to provide a composition with multiple specific characteristics for successful use a number of additives must be combined in proportions appropriate to provide the characteristics. The development of such compositions is thus expensive...
