Montecatini Edison

It is important to begin producing this additive as soon as possible. This is because die discovery of something new is frequently made by two or more independent investigators at about the same time, and the first producer sets the standards and gets the markets. In 1969 four chemical companies Standard Oil Co. (Indiana), DuPont, Phillips Petroleum, and Montecatini-Edison, were all claiming to be the inventor of polypropylene. At that time, the U.S. Patent Office had still not decided who would get the U.S. patent, even though the work had been done over 10 years before.5 Finally in December 1971 Montecatini-Edison received the patent. 

The second material to come onto the market was the Montecatini Edison fluoropolymer called Fomblin Z33,34 with the structure...

Polymer Samples. Commercial PVC, Sicron 548 FM, of the type Gs, 6361 112 (Montecatini Edison S.p.A., Milan) was chlorinated by four different heterogeneous processes, designated A, B, C, and D. A, B, and C are characterized by the presence of chloroform as swelling agent. In process D, PVC is chlorinated without swelling agent. 

In non-supported catalysts, most active centers (>95%) become encased within the growing polymer particle and thereby become unavailable for additional polymer formation. This results in low catalyst activity. A major improvement occurred in the early 1970s when supported Ziegler-Natta catalysts began to emerge. Leading polyethylene producers of the time (Shell, Solvay Cie, Hoechst, Mitsui and Montecatini Edison) developed many of these catalysts (8). Of course, most have morphed into present-day companies, such as LyondellBasell and INEOS.
