polyamidester as reologisk enrichment, a solution containing the means of enrichment and altered configurations

摘要

A polyamide (or oligomeric amide) ester rheological additive especially for organic solvent-based compositions comprises the reaction product of a defined polycarboxylic acid, a diamine, an alkoxylated polyol and a capping agent. The additive exhibits excellent efficiency and ease of dispersibility and is especially effective when first predispersed in an organic solvent. Organic solvent-based compositions which may be thickened by using the rheological additive are aliphatic, aromatic, and some moderately polar solvent-based compositions.
