POLYMER LATEX RECOVERED FROM CLEAN WATER EMULSION, PROCESS FOR THE RECOVERY OF A POLYMER LATEX PRODUCT FROM A CLEAN WATER EMULSION AND APPARATUS FOR THE CONCENTRATION OF CLEAN WATER EMULSES

摘要

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.
