## Abstract **Summary:** Monodisperse thermosensitive PSโNIPA coreโshell particles composed of a PS core and a crossโlinked PNIPA shell can be successfully synthesized by a novel method: photoemulsion polymerization. CryoโTEM images indicate clearly the coreโshell morphology of the PSโNIPA particle
A fundamental study about the characterization of a poly(Nisopropylacrylamide), poly(NIPAM), microgel, cross-linked with N,N -methylene bisacrylamide (BA), has been carried out. The anionic charge of this system was increased by copolymerization with 2-acrylamido-2methylpropanesulphonic (AMPS) acid.
