ETHYLENE-RICH DIENE TRIBLOCK POLYMER HAVING A STATISTICAL BLOCK AND TWO TERMINAL POLYETHYLENE BLOCKS
Publication number: 20240043600Abstract: A triblock polymer of formula B-A-B is provided. According to the formula, the symbol A represents a “central” block which is a statistical copolymer comprising units of a 1,3-diene and more than 50 mol % of ethylene units. The symbols B each represent an “end” block which is a polyethylene with a melting point of greater than 90° C. and a number-average molar mass of greater than or equal to 2000 g/mol and less than or equal to 10 000 g/mol. The polymer has improved rheological properties relative to a statistical copolymer based on ethylene and 1,3-diene of the same microstructure without changing its mechanical and dynamic or thermal properties.Type: ApplicationFiled: November 22, 2021Publication date: February 8, 2024Inventors: Nicolas BAULU, Christophe BOISSON, Franck D'AGOSTO, Damien MONTARNAL, Emma MORESO, Julien THUILLIEZ, François JEAN-BAPTISTE-DIT-DOMINIQUE -
Patent number: 11718692Abstract: A copolymer of ethylene and of a 1,3-diene of formula CH2?CR—CH?CH2 is provided. The ethylene units represent between 50 mol % and 95 mol % of the ethylene units and of the units of the 1,3-diene, and the units of the 1,3-diene of 1,2 and 3,4 configuration represent more than 50 mol % of the units of the 1,3-diene.

Publication number: 20220332878Abstract: A diblock polymer composed of a first block and a second block is provided. The first block is a statistical copolymer comprising units of a 1,3-diene and more than 50 mol % of ethylene units. The second block is a polyethylene with a melting point above 90° C. and a number-average molar mass greater than or equal to 2000 g/mol and less than or equal to 10 000 g/mol. Such a diblock polymer has improved rheology compared to a statistical copolymer of the same microstructure and of the same macrostructure as the first block of the diblock polymer.Type: ApplicationFiled: July 27, 2020Publication date: October 20, 2022Inventors: Emma Moreso, Julien Thuilliez, François Jean-Baptiste-Dit-Dominique, Christophe Boisson, Franck D'Agosto, Nicolas Baulu, Damien Montarnal

Patent number: 11326001Abstract: A copolymer of ethylene and of myrcene, in which the ethylene units represent between 50 mol % and 95 mol % of the ethylene units and of the myrcene units, and the myrcene units of 1,2 and 3,4 configuration represent more than 50 mol % of the myrcene units, is provided. Such a copolymer exhibits an improved compromise between the degree of crystallinity and the stiffness. It therefore makes it possible to widen the field of application of ethylene-rich diene copolymers in rubber compositions, and also to increase the production capacity of a unit for the synthesis of ethylene-rich diene polymers.Type: GrantFiled: March 18, 2019Date of Patent: May 10, 2022Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Vincent Lafaquiere, Emma Moreso

Publication number: 20220056175Abstract: A terpolymer of ethylene, of 1,3-butadiene and of an aromatic ?-monoolefin is provided. The terpolymer contains more than 60 mol %, preferably at least 70 mol %, and preferably at most 90 mol % of ethylene units, at most 10 mol % of aromatic ?-monoolefin units and 1,2-cyclohexanediyl units. Such a diene terpolymer rich in ethylene units has the advantage of exhibiting a reduced, or even zero, crystallinity.Type: ApplicationFiled: December 2, 2019Publication date: February 24, 2022Applicant: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Emma MORESO, Vincent LAFAQUIERE, Julien THUILLIEZ
