| Abstract: | Composite particles of PMMA-MAA/PS with microvoid morphology wereprepared by means of soap-free seed emulsion polymerization.The effect of average molecularweight of seed polymer and curing agent on particle morphology were studied under the obser-vation of TEM.Results show that the collective PMMA-MAA microdomain in the centergradually changes into dispersive spots with reduction in average molecular weight of the seedpolymer PMMA-MAA. |

| Keywords: | composite polymer particle seed emulsion polymerization morphology microsphere design |
