Leblanc s process had many disadvantages it was complicated, was dirty and polluting, and was materials and fuel inefficient. This set other scientists to working on development of a new process. In about 1872, Ernst Solvay developed what became known as the Solvay process, and this resulted in establishment of the French firm Solvay Cie. By 1890 the Solvay process dominated the world s alkali production.14 Leblanc s process was obsolete. 

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.
