Scientific and technical knowledge acquired in the last years by Montedison-Mitsui Research on high yield catalysts for olefin polymerization, as well as the ability to modify them as a function of the desired performances, has made it possible to design polyolefin production processes ensuring both very low production costs and high quality products. Pilot plant results confirm that the main key to the success of the new polyolefin processes is represented by the high quality, degree of activity and specialization of the catalysts. This major factor is associated with the reliability of plant technological approaches and macromolecular structures serving as model for the product synthesis. Another aspect of economic and social value is that the processes we are dealing with are absolutely irreproachable from the ecological point of view; they do not produce effluents at all. Data show conclusively that the type of catalyst and its utilization, therefore, determine the relationship between process, product quality and efficiency. Comparative investment costs are given. Homopolymer production costs are also presented.
