摘要： Core/shell additives, useful in modifying the processing and/or physical properties of poly(vinyl chloride) and other thermoplastic matrix polymers, are prepared separately at small particle sizes by emulsion polymerization, co-agglomerated, further encapsulated by a final shell, and isolated by spray-drying or coagulation. The isolated powders are readily re-dispersed to their original particle sizes in the matrix polymer.

摘要： Core/shell impact modifiers, useful in toughening poly(vinyl chloride) and other thermoplastics, are prepared at small particle sizes by an emulsion polymerization process, agglomerated by a novel technique which has little effect on emulsion solids, are further encapsulated by a final shell, and are isolated by spray-drying or coagulation. The isolated particles are readily re-dispersed to their original particle size in the matrix polymer.
