Polypropylene, a synthetic resin built up by the polymerization of propylene. One of the important family of polyolefin resins, polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required. It is also spun into fibres for employment in industrial and household textiles. Propylene can also be polymerized with ethylene to produce an elastic ethylene-propylene copolymer. Polypropylene is one of the most widely used polymer globally.
Polypropylene is mainly formed by the polymerization of olefin molecules. In the initial stage when no catalyst was used, the production of polypropylene was polymerized under high temperature and high pressure. Such a production process not only has a slow reaction speed, but also has a large number of harmful chain transfer reactions during the reaction process, resulting in a lot of useless At the same time, the high temperature and high pressure reaction conditions also require high equipment, which increases production costs; product quality is also affected, and it is very difficult to obtain high-quality polypropylene products.
In the production process of polypropylene, the addition of a catalyst can improve the polymerization environment of the molecules, accelerate the polymerization speed, and improve the quality of polypropylene. The most representative one is the Ziegler-Natta catalyst, which was invented by the German chemist Karl Ziegler and the Italian chemist Giulio Natta. They analyzed the mechanism of olefin polymerization. Adding a catalyst can improve the environment for olefin molecules to polymerize. Since then, the production of polymer materials has entered a rapid development track, which has greatly promoted the development of the polypropylene industry.
The application of Ziegler-Natta catalysts in the production of olefin products simplifies the production process. High temperature and high pressure conditions are no longer required in the production process, thereby reducing production costs and improving the product structure and nature a lot.
On the basis of the Ziegler-Natta catalyst, after continuous exploration and continuous improvement by researchers, the role of the catalyst is continuously improved. Now this catalyst system has been developed to the fifth generation. Due to production needs, new catalysts are also under constant research, and metallocene catalysts and late transition metal catalysts have emerged. The emergence of these catalysts has also greatly improved the performance of polypropylene and expanded polypropylene derivatives. The application space and prospects.
