ABSTRACT:
Polymer is recovered by ultrafiltration from a whitewater waste stream generated during the production of a polymer latex. The whitewater stream is circulated through an ultrafiltration system in laminar flow, under conditions of shear insufficient to destabilize the whitewater emulsion, and the recovered polymer is in the form of an emulsion which may be blended at significant levels into the original polymer latex without degrading its performance properties.
