**Abstract**
 Core-shell microspheres with a polybutyl methacrylate (BMA) core and a poly 3-(methacryloxypropyl)-trimethoxysilane (MATS) shell, were prepared with a methanol as the dispersion medium, by a successive seeding method under kinetically controlled conditions. To prepare core/shell (PA/PSi), the core was first synthesised by dispersion polymerisation and to form seeds. Addition of MATS monomer was started after 90-95% conversion of the BMA. The reaction was prolonged for a further 12 h to achieve complete consumption of the MATS monomer. Microspheres containing hydrophilic PBMA as the core and hydrophobic PMATS as the shell were successfully formed through the free radical of surface in the core. The particle morphology and size distribution were examined using TEM and particle size analysis techniques respectively. 22 refs.
