| 摘 要： | 聚丙烯在应力与温度等因素作用下晶型转变而引起的物理力学性能的变化尚未得到学术界与工程界的应有重视。通过熔体自由基接枝多功能团单体、添加高熔点的聚合物和α成核剂调控其聚集态结构,有效抑制了聚丙烯在应力作用下的晶型转变,改善了聚丙烯的疲劳稳定性,有助于增加其在工程应用中的使用寿命。

| Abstract: | The physical and mechanical changes due to the crystalline transition of isotactic polypropylene under different temperature and stress have not been received much due attention from the academic and engineering circles.The melt grafting polymerization with multifunctional vinyl monomer,polymer with high melting temperature,and alpha-nucleating agent were applied to modify the chain structure and crystalline behavior in order to regulate the aggregate structure of the polypropylene.The experimental results ... |
