Synthesis and characterization of chitosan grafted with polystyrene using ammonium persulfate initiator

Graft copolymerization of styrene from chitosan was prepared under various conditions using ammonium persulfate (APS) initiator. The grafting was found to be best at 1:3 chitosan:styrene weight ratio, 0.4 g APS and temperature 60 degrees C. The washed products were characterized by spectroscopic and...
