摘要:A process for the continuous synthesis of a modified diene elastomer comprising at least one silicon atom directly connected to the elastomer chain is provided. The process comprises polymerization by n reactors r1 to rn, considered to be continuous stirred-tank reactors equipped with an internal stirring system and arranged in series, n varying from 2 to 15. The reactor r1 is fed by an input solution comprising a solvent, one or more monomer(s), an anionic polymerization initiator chosen from lithium amides and a polar agent. The temperature of each reactor varies from 20° C. to 150° C. and is greater than or equal to the temperature of the reactor which immediately precedes it. The living diene elastomer obtained exhibits a polydispersity index varying from 1.1 to 1.7. The process further comprisesmodification of the living diene elastomer obtained in the preceding stage by a functionalization, coupling or star-branching agent.

摘要:Silylating grafting agents and methods for synthesizing the same. The grafting agents are used to produce functionalized polydiene polymers by modifying the backbone of the polymer. Methods for functionalizing a polydiene post-polymerization using hydrosilylation are described. Hydrosilylation provides an advantage of incorporating multiple functional groups on the backbone of the polymer which lead to improved properties, such as rolling resistance, wet traction and polymer filler interaction.
