Abstract

A process for producing polylactide-urethane copolymers, which comprises the step of contacting a polylactide having terminal hydroxyl groups, produced by contacting at least one lactide monomer with a diol or diamine, with a diisocyanate compound optionally in the presence of a second diol or diamine in the presence of a catalytic system under polymerisation conditions characterised in that the polylactide and the polylactide-urethane copolymers are produced by reactive extrusion.
