| Abstract: | In the extrusion process by adding undecylenic acid and initiator to the blend of starch and polyethylene to initiate the graft copolymerization of starch and undecylenic acid so as to decrease the hydrophilicity and improve the starch dispersion in polyethylene. The effects of undecylenic acid and various systems of initiator on the mechanical properties of the blend are studied. The results of tests indicate that the addition of undecylenic acid leads to a blend with stable phase, uniform phase distribution and strong adhesion strength. |
