The present invention relates to a copolymer comprising a copolymer chain A carrying a functional group B chosen from the group consisting of functional groups B1 and B2, the copolymer chain A being acopolymer chain comprising monomer units M1 and monomer units M2, M1 being a conjugated diene, M2 being a monomer chosen from the group consisting of the alpha-monoolefins, ethylene and mixtures thereof, B1 being chosen 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); and B2 being a functional group deriving from B1. A copolymer of this kind is synthesized using a transfer agent carrying the functional group B1 and a carbon-metal bond, the metal being an alkaline earth metal, zinc or aluminium. 本发明涉及包含共聚物链A的共聚物，所述共聚物链A带有选自官能团B1和官能团B2的官能团B，所述共聚物链A为包含单体单元M1和单体单元M2的共聚物链，M1为共轭二烯，M2为选自α-单烯烃、乙烯及其混合物的单体，B1选自N(SiMe)；N(SiMeCHCHSiMe)；对-CH(NMe)；对-CH(OMe)；对-CH(N(SiMe))；邻-CH-CHNMe；邻-CH-CHO
