preparation of multi hollow composite particles via dual seeded dispersion polymerization and study effect of initiator concentration on size and number of dent

Multi hollow like poly(styrene-acrylamide) p(S-AAm) particles were produced via dual seeded dispersion polymerization (DSDP) of 2(ethylhexyl methacrylate (EHMA) with PS and PAAM seed beads in the presence of saturated hydrocarbon droplets and evaporation of the hydrocarbon after the polymerization. The effect of different reaction conditions such as initiator concentration on the shape and stability of the produced particles was investigated. The result show that with decrease amount of initiator the size and number of dents decreased.
