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 -
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.

Patent number: 9315637Abstract: Junction-functionalized block copolymers can be used in forming nanostructures. A junction-functionalized block copolymer can include a first polymer block joined to a second polymer block by a junction, where the junction includes one or more electrostatically charged moieties. The block copolymer can include a moiety of formula (I): A-J-B??(I) where A is a first polymer block, B is a second polymer block, where the A block and the B block are chemically dissimilar, and J is a junction linking the A block to the B block, and including one or more electrostatically charged moieties.Type: GrantFiled: December 17, 2014Date of Patent: April 19, 2016Assignee: The Regents of the University of CaliforniaInventors: Damien Montarnal, Yingdong Luo, Craig J.
