α成核剂与HYBRAR对PP 结晶性能及形态的影响
关键字：聚丙烯，HYBRAR，α成核剂，结晶性能
聚丙烯（PP）作为用量较大的通用塑料之一，因其低廉的价格及良好的加工性能而受到青睐。然而，由于其抗冲击性能低，特别是低温性能较差等缺点，限制了其进一步应用。共混改性是完善PP 性能的有效手段，其中橡胶增韧改性PP的冲击性能在近30年来一直受到热切关注。HYBRAR是独有的异戊二烯技术开发的一种室温下缓冲高振动即减震的特殊热塑性弹性体，氢化的HYBRAR 与PP 具有很好的相容性，可以被用来生产透明性好，柔软...

EPDM 对微发泡PP泡孔形态的影响
关键字：聚丙烯，EPDM，发泡，流变性能
本文以三元乙丙橡胶（EPDM）为弹性体相，采用毛细管流变仪、动态流变仪、扫描电子显微镜(SEM)、偏光显微镜等对聚丙烯(PP)/EPDM共混物体系的熔体性能、泡孔形态进行了表征。结果表明，当EPDM含量低于10wt%时，PP/EPDM共混物具有和PP 相似的熔体粘度，但熔体强度比PP 低，这是因为当EPDM 含量低时，EPDM粒子以海岛状分布在PP基体中，增加了PP链段间距，使PP链段缠结降低，从而使体系的熔体强度也降低；当EPDM 含...

PP/纳米CaCO3中的界面相互作用
关键字：聚丙烯 纳米CaCO3 界面相互作用
由于纳米CaCO3（CC）的低成本，品质稳定，在高分子中得到广泛应用。国内外对PP/CC有许多已研究[1-5]。但其物理、力学性能与PP/CC中界面相互作用缺少系统研究。为提高PP/CC 力学性能和研究界面相互作用的影响，本文制备了三种相容剂（PP-g-MA、POE-g-MA和EVA-g-MA）改性PP/CC，重点研究了PP/CC中界面相互作用。
