MORPHOLOGY OF PMMA-MAA/PS COMPOSITE POLYMER PARTICLES
PMMA-MAA/PS复合乳胶粒的形态

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.
