文章摘要：
针对具有网状结构的PPO/SEBS--g--MAH共混合金冲击断面的形貌和微观形变过程,提出了“瞬间原位大取向”增韧模型. 该模型认为, 超韧PPO/SEBS--g--MAH的冲击断裂首先是弹性体周围产生微穴, 微穴诱发基体产生剪切带, 基体在剪切屈服过程中被网状的弹性体携带共同发生大的取向行为, 形成取向分子束, 从而吸收大量能量, 达到超韧水...

文章摘要：
用扫描电子显微镜(SEM)观察了PPO/SEBS和PPO/SEBS--g--MAH共混物的常温缺口冲击断面,发现PPO/SEBS共混体系的冲击断面上有大量韧窝; PPO/SEBS--g--MAH共混体系则呈现中心为棒, 四周为环的冲击断面形貌. 对PPO/SEBS--g--MAH冲击断面的应力发白区的SEM观察结果表明在冲击断面下方, 合金发生大...
