| Abstract: | The graft copalymer of acrylate acid (AA) with low molecular weight Polyethylene (LMPE) was synthetized with peroxidate as initiator in molten state. The giaft copolymer (LMPE g AA) was characterized by FTIR and a contract angle with glycerine. Small angle light scattering tensile strength and balancing torque measurement were used to study the effects of the LMPE g AA on the compatibility of the HDPE phase and the Mica phase. The results indicate that the non even structure coefficient of the HDPE/Mica alloy can be improved by LMPE g AA. Besides, it can also improve the tensile strength and the balancing torque of the HDPE/Mica alloy. |
