  • Preparation of stable dispersions of ethylene oxide polymers
    Patent number: 5480928
    Abstract: A process for producing a stable dispersion of ethylene oxide polymer which comprises contacting (a) a slurry of granular ethylene oxide polymer in a first inert normally-liquid hydrocarbon diluent, with (b) a second inert, normally-liquid organic diluent such as propylene glycol, and (c) a suspending agent, e.g., silica, (d) under agitation which is sufficient to provide intimate mixing of said ethylene oxide polymer and said suspending agent with said second diluent; and (e) recovering a stable dispersion comprising particulate ethylene oxide polymer and suspending agent in said second diluent.
