1.What is PP polymer?

A：Polypropylene (PP) is a thermoplastic "addition polymer" made of a combination of propylene monomers. It is used in a variety of applications, including furniture parts, automotive industry and other industries of plastic parts. Polypropylene was first polymerized in 1951 by two Phillips oil scientists, Paul Hogan and Robert Banks, and later by Italian and German scientists NATTA and Rehn. Less than three years after the Italian chemist Giulio Natta first polymerized it, the method became prominent as commercial production began. NATTA perfected and synthesized the first polypropylene resin in Spain in 1954. The crystallinity of polypropylene has aroused great interest. By 1957, its popularity had soared, and widespread commercial production began throughout Europe. Today, it is one of the most commonly used plastics in the world.
