Abstract
The present invention relates to a process for preparing a diene elastomer/polylactide copolymer, the weight percentage of polylactide being between 10% and 45% by weight, relative to the weight of the copolymer, characterized in that lactide, an elastomer functionalized by at least one group bearing at least one function capable of initiating a ring-opening polymerization of the lactide and a catalytic system are introduced into an extruder (A).
