Abstract

The present invention relates to a process for making gel-free functionalized anionic polymers using multi-alkali metal initiators which comprises: anionically polymerizing at least one monomer with a multi-alkali metal initiator in a hydrocarbon solvent, capping the polymer by adding to the polymer a capping agent that reacts with the ends of the polymer chains such that strongly associating chain ends are formed wherein a strongly associating gel is formed, and adding a trialkyl aluminum compound to the gel. According to a further embodiment, the invention relates to a gel-free process for making functionalized anionic polymers using multi-alkali metal initiators which comprises: anionically polymerizing at least one monomer with a multi-alkali metal initiator in a hydrocarbon solvent, adding a trialkylaluminum compound before or during polymerization or before or at the same time as the capping agent, and capping the polymer by adding to the polymer a capping agent which, in the absence of the trialkylaluminum compound, would react with the polymer chain ends to form strongly associating chain ends wherein a strongly associating gel would be formed. Further aspects of the invention relate to a process for making functionalised polymer from unfunctionalised polymer; to a process for making functionalised polymer from polymers that are functionalised with a different functionality; and to a process for hydrogenating the polymers prepared by the above processes.
