aqueous pour point depressant dispersion composition and method for inhibiting paraffin deposition or for improving oil flow properties

摘要

"aqueous pour point depressant dispersion composition and method for inhibiting paraffin deposition or for improving oil flow properties" The present invention relates to an aqueous pour point depressant dispersion composition comprising a thermoplastic polymer, preferably ethylene vinyl acetate (eva); a dispersing agent; Water; optionally an aqueous freezing point depressant and optionally a stabilizing agent, wherein the volumetric average particle size of the dispersed thermoplastic polymer is equal to or less than 1 micrometer and a method for preparing and using said composition. 1
