Effects of Swelling Processes on the Particle Morphology of Porous P(MMA-EGDMA) Particles via Seeded Two-step Swelling Method

1 Results Porous functional polymer particles have been drawing great interest for their applications in many fields such as ion exchange,polymeric carrier,biomedicine,biochemistry,cosmetics,plastic pigments,and were first prepared by suspension polymerization in 1 950 s.Since 1990's,some approaches such as seeded emulsion polymerization method,dynamic monomer swelling method,activated swelling method and multi-step seeded method[1-4] have been used by many researchers to synthesize this kind of polymer...
