ABSTRACT:
A composition is composed of a hydrophobically modified aminoplast polyether or hydrophobically modified non-urethane polyethers with a viscosity suppressing agent of cyclodextrins or derivatives thereof. A method for improving the pumpability and pourability of aqueous solutions of thickener of a hydrophobically modified aminoplast polyether or hydrophobically modified non-urethane polyethers which is provided by admixing a cyclodextrin with the thickener to form a complex of the cyclodextrin and thickener where the viscosity of the thickener is suppressed and adding the complexed admixture to an aqueous system containing a water-insoluble polymer wherein the cyclodextrin is decomplexed and the thickener becomes an effective thickener. An example of the uses for this composition and method is in film forming coatings such as latex paints.
