Abstract

The invention relates to alkyl- or aryl-terminated polyamide compositions and polyamide rheological additives that function as a sag/slump control agent and provide superior shear-thinning and viscosity recovery properties in systems that react with or are sensitive to water and other active hydrogen containing materials and systems that do not react with or are not sensitive to water or other active hydrogen containing materials, and are useful in sealants, caulks, adhesives and coatings.

Claims

1. A rheological additive providing viscosity control in resin or organic solvent systems comprising a monoamine capped non-reactive polyamide.

2. The rheological additive of claim 1 wherein the polyamide is prepared by reacting at least one polycarboxylic acid of the formula (I)

3. The rheological additive of claim 2 wherein the polycarboxylic acid is selected from the group consisting of dimerized fatty acids, trimerized fatty acids, dicarboxylic acids containing from 6 to 22 carbon atoms, and tricarboxylic acids containing from 6 to 22 carbon atoms.

4. The rheological additive of claim 3 wherein the polycarboxylic acid is selected from the group consisting of dimer acids, trimer acids, sebacic acid, azelaic acid and dodecanedioic acid.

5. The rheological additive of claim 2 wherein the monoamine is selected from the group consisting of saturated, ethylenically unsaturated and acetylenically unsaturated naturally occurring and synthetic primary and secondary monoamines containing from 8 to 24 carbon atoms.

6. The rheological additive of claim 5 wherein the monoamine is selected from the group consisting of octadecylamine, dodecylamine and oleylamine.

7. A sealant composition containing a rheological additive providing viscosity control wherein said rheological additive comprises the polyamide of claim 1.

8. A caulk composition containing a rheological additive providing viscosity control wherein said rheological additive comprises the polyamide of claim 1.

9. An adhesive composition containing a rheological additive providing viscosity control wherein said rheological additive comprises the polyamide of claim 1.

10. A coating composition containing a rheological additive providing viscosity control wherein said rheological additive comprises the polyamide of claim 1.

11. A paste composition containing a rheological additive providing viscosity control wherein said rheological additive comprises the polyamide of claim 1.
