A Brief History of Polypropylene Development

In 1954, G. Nata first polymerized propylene into polypropylene (using aluminum titanium chloride as a catalyst) and established the theory of directed polymerization, which attracted people's attention.
In 1957, Italian company Montecatini and American company Hecules established polypropylene production plants of 6000t/a and 9000t/a, respectively.
From the late 1960s to the mid-1970s, polypropylene entered a period of great development.
Since the 1980s, polypropylene production has been at the forefront of synthetic resins, and is now only lower than polyethylene, ranking second.
China began researching the production process of polypropylene in 1962. Since the 1980s, polypropylene has developed rapidly in China. China has introduced some advanced polypropylene production technologies and equipment, and has established a number of large and medium-sized polypropylene production facilities such as Yanshan, Yangzi, and Liaoyang. A large number of small bulk polypropylene production facilities have also been built in various regions, which has played a certain role in alleviating the supply-demand contradiction. The significant increase in production scale has prompted China's polypropylene resin production to enter a rapid development stage
