Polystyrene was reacted with chloromethyl methyl ether in the presence of zinc chloride as catalyst leading to the successful produce of chloromethylayed polystyrene (CMPS).Then CMPS was used as macroinitiator to synthesize a photo-crosslinkable graft polystyrene in which the side chain was formed by monomers of methyl methacrylate and 4-methacryloyloxystyryl phenyl ketone by atom transfer radical polymerization with CuCl/bpy as catalyst.Structure of the result polymer was confirmed by means of FT-IR,~1H NMR.The thermal stability of the graft polymer was investigated by thermogravimetric analysis and differential scanning calorimetry.The results showed that this graft polymer had high thermal stability and good photosensitivity.
