N/A We investigated the effect of 1-octhanol and PVP(poly(N-vinyl-2-pyrrolidon) K-90) on the changes of shape, size distribution, porosity of PolyHEMA beads, which were prepared by suspension polymerization. As the concentration of 1-octhanol increases, the shape of PolyHEMA beads becomes irregular and the average size of the beads grows. Also the porosity and the average radius of PolyHEMA beads are increased. Increased PVP concentration makes average radius small but the effect can be ignored when the concentration is over 3 %. The porosity gets a gains of nearby 25 % as its concentration increases. But it does not affect on the shape.
