A process to produce a dispersion comprising feeding ethylcellulose polymer and a dispersant into a melt and mix zone of an extruder wherein the ethylcellulose polymer and dispersant are melted and mixed together to form a melt; conveying the melt to an emulsification zone of the extruder in which the temperature and pressure are controlled; feeding a base and water into the emulsification zone wherein the melt is dispersed to form a high internal phase emulsion; conveying the emulsion to a dilution and cooling zone of the extruder; and feeding water into the dilution and cooling zone to dilute the high internal phase emulsion thereby forming an aqueous dispersion is provided.

Graft copolymerized maleimide-modified, impact resistant monovinylidene aromatic copolymer compositions have substantially improved impact strength and fatigue resistance properties when the swelling index thereof is 12 or greater and when the numerical difference in maleimide monomer content as between the grafted copolymer and matrix copolymer portions thereof differ by no more than 9 percentage points from each other. Such compositions are conveniently prepared by mass, solution or mass/suspension graft copolymerization processes and by deferring the addition of at least about 30 percent of the maleimide monomer ingredient to a point in the process after (and preferably only shortly after) phase inversion of the dissolved impact modifying rubbery polymer ingredient.
