The problem of synthesis of polymer suspensions with a narrow particle size distribution is relevant, since the field of their practical application is extremely wide. They are used as calibration standards in electron and optical microscopy and light scattering, for determining the pore size of filters and biological membranes, as model colloids, for studying the kinetics and mechanism of film formation from latex, as well as as polymer carriers of biological ligands in immunochemical studies [1].

The narrow particle size distribution of poly (vinyl silicone) microspheres were prepared by the hydrolysis-polycondensation method with vinyl silane (VTMS) as raw materials. And the influences of pH value, oil/water ratio on the morphology, particle size and distribution of the microspheres were studied. The results shows that the particle size of microspheres decrease with the increasing of the PH value of polymerization, and the particle size has no specific linear relationship with the PH value of hydrolysis reaction, while the oil-water ratio is smaller, single particle size distribution is more narrow, more uniform distribution.
