Abstract: The homogeneous graft copolymerization of nitrocellulose with methyl methacrylate has been carried out and the mechanism has been evaluated by FTIR, SEM and TEM techniques. It is suggested that the graft copolymerization might proceed through denitration of nitrocellulose and take place not only on the surface of nitrocellulose but also in some oriented crystalline rigion of nitrocellulose polymer.

Key words: nitrocellulose, methyl methacrylate, homogeneous graft copolymerization, mechanism
