Study on the Synthesize of Thermoplastic Carboxymethyl Cellulose with Graft Copolymerization

Thermoplastic of carboxymethyl cellulose graft methyl aery late (CMC-g-MA) using ammonium persulfate (APS) as an initiator was carried out in an aqueous solution. The percentage grafting percentage (%G) is affected by increasing reaction time, concentration of monomer and initiator, and reaction temperature. These graft copolymers were characterized by infrared spectroscopy, differential scanning calorimetry. Experiments showed that the optimal conditions for grafting were: ammonium persulfate of 150 mg; methyl acrylate of 40 mL; reaction time of 4 hour and temperature of 70°C.
