  • Patent number: 9315590
    Abstract: 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%.
