摘要： The present invention relates to a novel organometallic compound based on a divalent metal belonging to the 2nd column of the Periodic Table that can be used as an alkylating agent in a catalytic system based on a rare-earth metal. This novel compound corresponds to the formula: in which, M is a metal belonging to the 2nd column of the Periodic Table, chosen from Be, Mg, Sr, Ba, and Ra; R1, R2, R3 and R4 are hydrogen atoms or alkyl or aryl substituents, optionally bonded together to form at least one ring or at least one aromatic ring; R and R′ denote alkyl or aryl substituents; L is a Lewis base; x is an integer from 0 to 4; m is an integer greater than or equal to 0; and n is an integer greater than or equal to 1.

摘要： The present invention relates to a novel catalytic system for polymerization, and more particularly for preparing conjugated diene polymers bearing a polar function at the chain end. This catalytic system is based on a metal salt of a rare-earth metal and, as alkylating agent, an organometallic compound based on a metal belonging to the 2nd column or the 13th column of the Periodic Table, capable of transferring a polar function to the diene elastomer during the conjugated diene polymerization step. The novel catalytic system makes it possible to reduce the steps for synthesizing a chain-end functionalized elastomer, while ensuring optimal functionalization, advantageously close or equal to 100%.
