ABSTRACT:
A method for stabilizing the electrolyte content of latex composition baths in which, preferably, the bath is flowingly contacted with the outside of a tubular filtration membrane having pores smaller than the latex micelles, and partly deioized water flows through the center of the tubular membrane at a rate sufficient to cause a pressure differential and thus effect ultrafiltration removal of electrolytes.
