| 摘 要： | 通过严格控制工艺条件，得到了不同分散相含量和不同粒径的ＰＰ／ＥＰＤＭ／ＨＤＰＥ和ＰＰ／ＥＰＤＭ共混体。利用ＳＥＭ分析了ＰＰ／ＥＰＤＭ／ＨＤＰＥ的结构特点，通过测量Ｉｚｏｄ缺口冲击强度，得到了ＰＰ／ＥＰＤＭ／ＨＤＰＥ的脆韧转变主曲线，证明其符合脆韧性转变规律；同时利用ＳＥＭ照片，分析了主曲线不同区域的增韧机理。

| Abstract: | PP/EPDM/HDPE and PP/EPDM blends including different content of disperse phase and various particle size were attained under different blending condition. Morphology and properties of PP/EPDM/HDPE blends were investigated with scanning electronic microscope(SEM). Izod impact strength of blends were tested, and the brittle ductile transition master curve for PP blends. |
