The copolymerization reactivity ratios of vinyl-containing polysiloxane(SV) with styrene(ST),methyl methacrylate(MMA) or n-butyl methacrylate(BMA) were measured using Fineman-Ross method,and the results were:r_ST=1.45 and r_SV=1.08 for ST-SV,r_MMA=0.78 and r_SV=2.01 for MMA-SV,r_n-BMA=0.46 and r_SV=3.49 for BMA-SV,respectively.The reactivity ratios between vinyl-containing polysiloxane and vinyl monomers had a strong effect on the morphology of the particles prepared by the seeded emulsion polymerization.
