The Synthesis of Polypropylene Particles with Gas Phase Polymerization
Abstract：The reachpaper instruction the polypropylene is polymerized by propylene with the solicitation of homemade global laden catalyst. We design and construct a suit of polymeric equipment which could polymerize alkenes gas automatically. This equipment contains a depurative system of ethylene、propylene、hydrogen and nitrogen. At the same time, the equipment contains a metrical system of pressure and flux which is controlled by computer. Also, it contains a 2L retort and propylene still. The reaction system is leak hunted before polymerization. Then it is heated to 82℃ and depurated for 8 hours in vacuum. And the system is replaced by high purity nitrogen during the depurative process. Also we keep constant temperature and isobaric during the polymerization and trace the polymeric speed by computer.
