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