Study on Graft Copolymerization of Maleic Anhydride onto Ground Rubber Tire

Abstract:

The graft copolymerization of maleic anhydride (MAH) onto ground rubber tire (GRT) was investigated through solvothermal synthesis route using free radical initiator. The effects of solvents, initiators and their concentration, and GRT mesh size on the grafting yield (GY) were studied, and the optimal conditions were concluded. The results showed that the high GY was obtained by using toluene as solvent, 1% azobisisobutyronitrile as initiator, and GRT fine powder as raw material. Infrared spectra and X-ray photoelectron spectra confirmed that MAH was successfully grafted onto the GRT molecules. The thermogravimetric analysis revealed that the thermal stability of graft GRT (GRT-g-MAH) is better than that of GRT slightly. The blending experimental results suggest that the GRT-g-MAH can be used as a compatilizer for GRT/HDPE blends.
