nano porous polymer beads based on cross-linked poly(styrene -co-butylacrylate) prepared through suspension polymerization for extraction of anthocyanin

Porous polymer beads can be efficiently used to separate herbal compounds. in order to improve mechanical behavior of polymer beads and resistance against acidic and basic conditions, a monomer with low glass transition temperature (tg) value like butyl acrylate used in terpolymerization. poly(styrene-co-butyl acrylate) cross-linked by divinylbenzene (dvb) were synthesized via suspension polymerization. dodecane used as a progen solvent. scanning electron microscopy (sem) images were confirmed modifying of surface polymeric beads.
