Polypropylene is in many aspects similar to polyethylene, especially in solution behaviour and electrical properties. Syndiotactic polypropylene was also first synthesized by Natta.Ĭhemical and physical properties This pioneering discovery led to large-scale commercial production of isotactic polypropylene by the Italian firm Montecatini from 1957 onwards. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. Paul Hogan and Robert Banks first demonstrated the polymerization of propylene in 1951.
