Abstract: The anion starch microspheres(PSM) have been synthesized from starch or starch derivatives by the counter suspension crosslinking polymerization in the presence of POCl3 as the crosslinking agent.Another anion starch microspheres(TSM) are made of neutral starch microspheres by the secondary polymerization and anionization using Na3P3O9 as the crosslinking agent.Their surface morphology, size distribution, characters of swelling and adsorbability for drug carrying have been studied in this paper.

Key words: Starch, Microsphere, Suspension crosslinking polymerization, Adsorbability
