In order to improve the performance of PET materials,the grafted elastomer POE-g-GMA was added to polyethylene terephthalate(PET)by melt blending method.The effects of different amounts of grafted elastomers on the structure and properties of PET materials were investigated.The results show that with the increase of the volume fraction of the grafted elastomer POE-g-GMA,the impact strength of the material increases first and then decreases,and the tensile properties slightly decrease.The finite element analysis verifies that the pressure-bearing performance of the modified PET material did not show a significant decrease.
