Abstract:
The use of a catalytic ring-opening lactide and glycolide (co)oligomerization system consisting of a strongly acidic ion-exchange resin-type polymeric catalyst and a (co)oligomerization additive, and a lactide and glycolide (co)oligomerization method using said catalytic system, are disclosed.
