中文摘要：

利用基本断裂功和缺口冲击强度，评价了在拉伸和冲击应力作用下，异氰尿酸三缩水甘油酯（TGIC）对聚对苯二甲酸丁二醇酯（PBT）／乙烯-1-辛烯共聚物（POE）共混物（90／10，wt／wt）断裂韧性的影响。结果表明，当POE中填加的TGIC达到5phr时，能够有效改善PBT和POE的界面粘接。与未填加TGIC的体系相比，其比基本断裂功提高了36％，而缺口冲击强度则提高了近47％。

英文摘要：

This passage uses the essential work of fracture （EWF） and notch impact strength to evaluate the influence of TGIC on fracture behavior of PBT/POE blends under the effect of tensile stress and impact stress. The results indicate that when POE is added by 5 phr TGIC, the interface bonding between PBT and POE will be improved efficiently. Compared with the system without TGIC,its specific essential work of fracture is improved by over 36% ,and its notch impact strength increases nearly by 47%.
