Firstly, micron-size monodisperse polystyrene particles were prepared by emulsifier-free polymerization. Then the photo-initiator with double bond and ester group were attached on the surface of the PS particles by copolymerization using "starve" addition together with styrene. Finally both poly and poly(N-isopropylacrylamide) as hybrid hairy homopolymers were grafted on the surface of the PS particles by "grafting from" photo-initiation with sequential addition of AA and NIPA.
