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 solution containing 0.5 percent or more of an inorganic salt. The invention is also directed to salt sensitive emulsion polymers containing a water-dispersible polymer having a Tg of less than 25° 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.
