The blends of PE-g-MAH and gelatin were prepared by melting process and the compatibility of PE-g-MAH and gelatin in blends were characterized. The results of FTIR showed that the characteristic absorption band peaks of amine and amide groups of gelatin were shifted in PE-g-MAH/Gelatin blends, the equilibrium values of torque were higher with the increase of blending temperature, which proved that graft copolymer PE-g-MAH-g-gelatin was formed during the preparation process, and the amount of PE-g-MAH-g-gelatin was increased with increasing the amount of PE-g-MAH. SEM micrographs exhibited that there was PE-g-MAH-g-gelatin formed in surface of gelatin phase.

通过红外光谱分析、HAAKE流变分析、抽提等实验证明：共混物中明胶的氨基、酰胺基团吸收峰峰位发生了明显的变化；在熔融共混过程中，随着温度的提高，平衡扭矩增大；明胶与PE-g-MAH发生了反应形成PE-g-MAH-g-明胶接枝共聚物，而且随着PE-g-MAH用量的增加，形成接枝共聚物的量也提高；SEM的实验结果表明，在明胶的表面确有接枝物形成；通过DMA测试共混物的玻璃化转变温度，发现两组分的玻璃化转变温度差值减小，二者的相容性提高，实现了共混体系的自增容。

The mechanical properties of the modified material were tested, and the thermal stability of the modified EP blend was also investigated by TG. The results indicate that the graft copolymerization between PU and EP effectly inforces the miscibility of the PU/EP system. Compared with the properties of pure EP, the impact strength and tensile strength of the PU/EP with high thermal stability are markedly enhanced, and the fracture surface of the PU/EP system displays tough fracture features.

研究结果表明：PU和EP分子链之间存在着化学接枝反应，能有效地改善PU/EP体系中PU和EP分子间的相容性及相互贯穿；与TDE-85与E-51的混和环氧树脂比，PU改性TDE-85与E-51的混和环氧树脂仍然具有很强的耐热性能，并且冲击强度、拉伸强度均获得显著提高；PU/EP体系断口裂纹呈明显的韧性断裂特征，说明TDE-85与E-51的混和环氧树脂PU改性增韧效果明显。
