Title: Antonio Cassata: Innovator in Polymerization Processes
Introduction
Antonio Cassata is a notable inventor based in Milan, Italy. He has made significant contributions to the field of polymer chemistry, particularly in the stereoregular polymerization of alpha-olefins. With a total of 7 patents to his name, Cassata's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is a process for the stereoregular polymerization of alpha-olefins. This process involves the use of highly active and stereospecific new catalysts. These catalysts are derived from the reaction of a specific Al-alkyl compound, which may exist partially as a complex or a substitution reaction product with an ester of an oxygenated organic or inorganic acid. The catalysts are characterized by a surface area exceeding certain values or displaying a particular X-ray spectrum. They are produced by contacting a Ti halogenated compound, preferably in the form of a complex with an electron-donor compound, with a support that includes a Mg or Mn bihalide in an activated condition. The ratio of the Ti compound to the g moles of the ester and the electron-donor compound is maintained at less than 0.3.
Another patent by Cassata also focuses on the stereoregular polymerization of alpha-olefins, utilizing a similar approach with highly active catalysts. In this case, the catalysts are obtained from the reaction of an Al-alkyl compound with a supported component characterized by specific surface area and X-ray spectrum properties. The ratio of the Ti compound to the g moles of the electron donor compounds is again kept below 0.3.
