摘要：

The penetration/release behavior of various solvents into/from the hollow of micron-sized monodispersed cross-linked polystyrene (PS)/polydivinylbenzene (PDVB) (1/5.5, w/w) composite particle was examined. The hollow particles were produced by seeded polymerization utilizing the dynamic swelling method which the authors proposed earlier. The penetration into the hollow was affected by viscosity of the solvents and its affinity for the base polymers. Toluene saved in the hollow was released slowly. These results suggest that there is a possibility to apply such hollow particles as a controlled release material. (C) 1999 Elsevier Science B.V. All rights reserved.
