摘要
Carboxymethyl cellulose and methyl methacrylate graft copolymers (CMC-g-PMMA) were synthesized by using potassium persulphate (KPS) as initiator. These graft copolymers were characterized by Fourier transform infrared spectra (FTIR), thermogravimetric analyses (TGA), and differential scanning calorimeter analyses (DSC). In addition, the nonisothermal thermal decomposition kinetics of copolymers was studied. The experimental results indicated that in the temperature range from 300 degrees C to 450 degrees C, the copolymer had a mass loss. The activation energy was 41.96 kJ/mol, and the logarithm of the Arrhenius coefficient (lnA) was 17.31.
