Abstract: Disclosed is a polymer additive composition and solution of the additive having more than about 5 w% solubility in a mixture of water and water soluble organic compounds comprising: a substantially water insoluble polymer additive capable of forming a salt, the polymer additive having less than about 1 w% water solubility, and a counterpart salt forming species. A process for using these polymer additive compositions and solutions is disclosed wherein the additive or the additive solution is added prior to or optionally during or optional after a polymerisation process to form polyamides or polyesters.

Abstract: The present invention relates to a process for making a hydrophilic polyamide without excessive foaming by delaying the introduction of the hydrophilic monomer. The hydrophilic monomer may be added to the polymerization process after at least a portion of the water has been removed from the process.
