Hydrogel microspheres preparation of monodisperse hydrogel microspheres of submicron or micron size

Abstract

Precipitation polymerization of acrylamide derivatives in water resulted in the formation of monodisperse submicron particles. Repetitive seeded polymerizations using the product of precipitation polymerization or precipitation polymerization in ethanol–water media gave larger monodisperse particles. Especially, the latter was very effective for the preparation of micro-size particles. © 1988 The Society of Polymer Science, Japan.
