随着聚烯烃生产和科研的不断发展,人们试图通过控制催化剂的颗粒形态来控制所需要的聚合物的颗粒形态。这一课题的研究无论在理论上或生产实践上都有着重要的意义,从而引起了各国科学工作者的极大兴趣。 本实验采用氯化镁作载体,经和铝、有机硅和钛等各自的化合物在振动磨中研磨制得的 As polyolefin production and research continue to evolve, one attempts to control the particle morphology of the desired polymer by controlling the particle morphology of the catalyst. The research on this topic has important meanings both in theory and in production practice, which has aroused great interest of scientists from all over the world. In this experiment, magnesium chloride as a carrier, and aluminum, silicon and titanium and other compounds were ground in a vibration mill
