摘要： 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.

摘要： A copolymer of a 1,3-diene and of an olefin selected from the group consisting of α-monoolefins, ethylene and mixtures thereof is provided. The copolymer bears, at one of its chain ends, an alkoxysilyl or silanol function, functional group F1, and the copolymer is different from a copolymer of a 1,3-diene and a vinylaromatic monomer.

摘要： A copolymer comprising a copolymer chain A bearing a function B selected from the group consisting of the functions B1 and B2, the copolymer chain A being a copolymer chain comprising monomer units M1 and monomer units M2, M1 being a conjugated diene and M2 being a monomer selected from the group consisting of α-monoolefins, ethylene and mixtures thereof, B1 being selected from the group consisting of N(SiMe3)2; N(SiMe2CH2CH2SiMe2); para-C6H4(NMe2); para-C6H4(OMe); para-C6H4(N(SiMe3)2); ortho-CH2-C6H4NMe2; ortho-CH2-C6H4OMe; C6F5; C3F7; C6F13; CH(OCH2CH2O); B2 being a function that is derived from B1, is provided. Such a copolymer is synthesized by using a transfer agent bearing the function B1 and a carbon-metal bond, the metal being an alkaline-earth metal, zinc or aluminium.
