Abstract
The present invention relates to a method for preparing a copolymer from at least one cyclic monomer selected from: a lactone, a lactam, a carbonate, a lactide and a glycolide, an oxazoline, an epoxide, a cyclosiloxane, comprising the step consisting of reacting said cyclic monomer in the presence of a substituted phosphorus-containing compound.It also relates to the polymer composition obtained according to this method, as well as the uses thereof, notably as antistatic additives, biocompatible materials, as membranes for treatment of effluents or in electrochemical systems for energy storage.
