The seeded microemulsion polymerization of butyl acrylate was studied
with gamma-rays. The hydrodynamic diameter and its distribution of pol
ymer particles in the seeded microemulsion before and after polymeriza
tion were determined with photon correlation spectroscopy (PCS). Thoug
h there were micelles in the microemulsion, it was found that new part
icle formation could be ignored during polymerization. The polymerizat
ion kinetics of the seeded microemulsion was investigated. The polymer
ization rate increases with the dose rate and added monomer content an
d decreases with the seed fraction. It was completely different from t
hat for seeded emulsion polymerization. (C) 1998 John Wiley & Sons, In
