Modification of starch is increasingly being studied and starch is used for applications in which synthetic polymers have traditionally been the materials of choice. In this work the surface of starch was successfully modified by the polymerization of polystyrene and polyacrylamide by atom transfer radical polymerization (ATRP) method in dispersion medium. For this propose the bromoactylated starch was prepared by the reaction between hydroxyl groups of starch and the bromoacetyl bromide in DMA/LiCl (5%) in the presence of pyridine. The bromoactylated starch acts as macroinitiator in ATRP of styrene. The polymer chains' growth on surface of starch was clearly showed by the AFM images. Other analyses were used in this work such as FT‐IR, DSC, and TGA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
