Title:
HIGHLY FUNCTIONAL POLYMER LATEX
Document Type and Number:
WIPO Patent Application WO2002079270
Kind Code:
A3
Abstract:
The present invention is directed to an ethylene-vinyl acetate emulsion polymer having at least 55 percent by weight of ethylene, which is water-dispersible, yet non-dispersible in an aqueous solutions containing 0.5 percent or more of an inorganic salts. The invention is also directed to salt sensitive emulsion polymers containing a water-dispersible polymer having a Tg of less than 25 DEG C, which are non-dispersible in aqueous solutions containing 0.5 weight percent or more of an inorganic salt. The invention is also directed to an ethylene/vinyl acetate emulsion polymer having at least 55 percent by weight of ethylene, and a process for producing said emulsion polymer.
