Effect of crosslinker on characteristics of acrylic acid microgels prepared by precipitation polymerization

Hydrogel microspheres were synthesized by precipitation polymerization of acrylic acid. Nearly monodisperse microgels having diameters around 495 nm were obtained. By using suitable quantity of crosslinker we could control the particle size distribution and the mean particle size of microgels. In this study we found out that increasing the amount of crosslinker, results in smaller and more uniform hydrogel particles
