Title: Pierre M Mangin: Innovator in Elastomeric Copolymers and Catalysts
Introduction
Pierre M Mangin is a notable inventor based in Martigues, France. He has made significant contributions to the field of polymer chemistry, particularly in the development of elastomeric copolymers and catalysts for olefin polymerization. With a total of 10 patents to his name, Mangin's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents involves elastomeric copolymers of ethylene and propylene. This invention focuses on copolymers where the weight proportion of ethylene units ranges from 34% to 67%, while the proportion of propylene units is between 33% and 66%. These copolymers are characterized by having at least 60% of the propylene units arranged in sequences of three or more. Additionally, their fusion enthalpy, measured after a specific heat treatment, is lower than 15 cal/g, typically ranging from 5 to 10 cal/g. These copolymers are particularly useful for producing isotactic polypropylene compositions.
Another significant patent pertains to a catalyst for the polymerization of olefins based on magnesium. This invention describes solid catalysts that primarily consist of magnesium compounds and transition metals from specific sub-groups of the periodic table. The catalyst is created by preparing a solid magnesium compound, along with monohalogenated hydrocarbons and halogens or organic derivatives of transition metals in a high valency state. This innovative approach enhances the efficiency of olefin polymerization, especially for ethylene.
