Abstract

The present invention is directed to a composition comprising an amide moiety containing polyol wherein the amide moiety is formed by the reaction of an amine reactive compound with an amine containing compound.

First claim

What is claimed is:

1. A molded polyurethane article comprising a polyurethane elastomer that comprises the reaction product of a mixture comprising an isocyanate compound and an amide moiety containing polyol wherein the amide moiety is the reaction product of an amine reactive compound with an amine containing compound wherein the amine reactive compound is selected from the group consisting of 3-hydroxy butyrate esters, 3-hydroxy butyric acids, lactic acid esters, and combinations thereof; wherein the polyurethane elastomer is not an adhesive or a coating composition; and wherein the molded polyurethane article has a minimum tear strength of 400 lbs Force/in.

2. The molded polyurethane article according to claim 1 , wherein the amine containing compound comprises a primary amine, a secondary amine, or combinations thereof.

3. The molded polyurethane article according to claim 1 , wherein the amine containing compound comprises an aliphatic amine.

4. The molded polyurethane article according to of claim 1 , wherein the amine containing compound comprises N,N′-bis(3-aminopropyl)methylamine, N,N′-dimethylethylene diamine, neopentanediamine, 4,4′-diaminodiphenyl methane, 2-methylpentamethylenediamine, polyetheramine, or combinations thereof.

5. The molded polyurethane article according to claim 4 , wherein the polyetheramine comprises
(a) an amine having the structure

wherein n is about 2.5 to about 68,
(b) an amine having the structure

wherein m is about 2 or about 3;
(c) an amine having the structure

where R is H or C 2 H 5 , k is 0 or 1, and the total of x, y, and z is 5 to 85; or
combinations of (a), (b), and (c).

6. The molded polyurethane article according to claim 1 , wherein the composition is at least partially foamed.

7. The molded polyurethane article according to claim 1 , wherein the composition is free of compounds containing polyester moieties.

8. The molded polyurethane article according to claim 1 , wherein the amine reactive compound is selected from the group consisting of 3-hydroxy butyrate esters, lactic acid esters, and combinations thereof.

9. The molded polyurethane article according to claim 8 , wherein the reactive group ratio of the amide moiety containing polyol to isocyanate compound ranges from 0.1 to 10:1.

10. The molded polyurethane article according to claim 9 , wherein the isocyanate compound is an isocyanate terminated pre-polymer compound.

11. The molded polyurethane article according to claim 10 , wherein the isocyanate terminated pre-polymer is prepared by reacting a molar excess of polymeric polyisocyante with one or more polyols.
