Abstract
The present invention relates to a process for preparing functionalized polymers having at least one double bond and functional groups containing a carbonyl radical along their chains. The process involves (a) subjecting a starting polymer comprising at least one double bond, in an inert hydrocarbon solvent, to a hydroalumination or carboalumination reaction along its chain by adding an agent derived from aluminum to the starting polymer, (b) adding to the product obtained in (a) at least one electrophilic agent that reacts with said agent derived from aluminum and (c) stopping the functionalization reaction of (b) and recovering the functionalized polymer.
