Encapsulated micro-agglomerated core/shell additives in poly(vinyl chloride) blends |
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.
