Abstract: This invention provides processes for isolating particles from an emulsion including the steps of: (a) forming an emulsion having a solid component having a population of particles, a liquid component, and a first ionic forming compound, wherein the presence of the first ionic forming compound in the emulsion does not result in the coagulation of the population of particles contained therein; (b) obtaining a composition having a second ionic forming compound which, by itself, is not sufficient to result in the coagulation of the population of particles contained in the emulsion; and (c) mixing the emulsion and the composition having the second ionic compound such that the first ionic forming compound reacts with the second ionic forming compound to form a coagulating agent which results in the coagulation of the population of particles. The invention also provides processes for preparing a polymer matrix system using the aforementioned process for isolating particles from an emulsion.

Abstract: The plastics additives powder compositions of the present invention are provided as powder particles having impact modifier particles and processing aid particles which are coagulated and dried. When blended in thermoplastic resins, such as PVC, the subject plastics additives powders both increase the impact strength and improve process efficiency and melt strength. The impact and processing properties achieved by the present invention are more efficient than using separate impact modifier and processing aid powders. The method of preparing the powder compositions of the present invention also enable impact modifier particles having rubber weight fractions greater than 88% to be isolated as free-flowing powders.
