The results show that the alloys are composed of LaNi5 as matrix and LaNi3 as secondary phase. With the increasing Sm substitution for La, the unit cell volume of matrix of the alloys shrinks linearly and both the hydrogen storage capacity and discharge capacity decrease. When the Sm substitution is 0.1, 0.2 and 0.3, the discharge capacity decreases from 380 mAh/g to 370(362), 355(334) and 329(295) mAh/g, respectively. However, the rate performance and cycle stability is improved. After 100 cycles, the capacity loss decreases from 20% to 18%(17%), 16%(14%) and 13%(11%).

结果表明：该合金是由LaNi5主相和LaNi3第二相构成；随著Sm取代La量的增加，合金主相单胞体积线性收缩，合金储氢量和放电容量减小，当Sm取代量分别为0.1、0.2、0.3时，合金容量由380 mAh/g分别减小到370(362)、355(334)、329(295) mAh/g，但高倍率放电能力和循环稳定性得到改善，100次循环后的容量损失率由20%分别降低到18%(17%)、16%(14%)、13%(11%)。

A study of phase morphology of PBT/POE-g-MAH/nano-CaCO3 composite by means of scanning electron microscopy showed that the domains size of nano-CaCO3 capsulated by POE-g-MAH elastomer in composite when PBT was mixed directly with POE-g-MAH and nano-CaCO3 together or with nano-CaCO3 capsulated by POE-g-MAH elastomer is large.

采用熔体流动速率较低的EPS30R与纯POE-g-MAH共混制备的增韧改性剂，在PBT基体中的分散相变得粗大且不均匀，共混物的脆韧转变推迟。SEM显示，纯POE-g-MAH增韧剂使PBT共混物发生脆韧转变时，弹性体分散相颗粒产生塑性变形，诱发基体屈服而吸收能量。

When the concentration of MAH is higher than that of St, some MAH monomer reacts with St to form SMA, others can directly grafts onto PP macroradicals. When the amount of St added is higher than that of MAH, part of St monomer may preferentially react with PP macroradicals to form more stable styryl macroradicals, while others copolymerize with MAH, yielding SMA. MFR of the grafted PP is lower in this case. It is considered that MFR of the grafted PP is decided by concentration of free monomers, or, number of grafting reactive species. FTIR analysis confirmed the above mechanism.

当MAH单体用量多于St单体时，一部分MAH单体与St反应生成SMA，另一部分可直接与PP大分子自由基进行接枝反应；当St单体用量多于MAH单体时，除与MAH反应生成SMA之外的St单体可先与PP大分子自由基反应，并起到稳定PP自由基的作用，这时接枝物的MFR较小，亦即接枝物的MFR与体系中可进行接枝反应的活性种数目有关。

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.

It was shown that the absorption peaks of amine and amide groups of gelatin were shifted in HDPE/PE-g-MAH/Gelatin blends because of the reaction of PE-g-MAH with gelatin. The addition of PE-g-MAH made the increase of HDPE glass transition temperature. The compatibilizing effect of PE-g-MAH was due to the crystal compatibility produced by forming the co-crystals of HDPE, PE-g-MAH and PE-g-MAH-g-gelatin. The blends of EAA and gelatin were prepared by melting process and the compatibility of the blends was also studied. The FTIR results showed that absorption peaks of amine and amide groups of gelatin were shifted in EAA/Gelatin blends.
