摘要： The invention concerns a method for obtaining oxacarbonyl polymers comprising steps which consist in: providing at least monomers comprising at least a cyclic oxacarbonyl function, an initiator, and in polymerising or copolymerising said monomers, in bulk or in solution, the initiator being selected among bicyclic guanidine compounds of formula (I) or (II) wherein one and/or the other of the cycles can be substituted, in at least any one of positions 2, 3, 4, 8, 9 and 10 of formula (I) or in at least any one of positions 2, 3, 7 and 8 of formula (II), by at least a radical selected among the alkyl groups with 1 to 6 carbon atoms, the cycloalkyl groups with 5 to 7 carbon atoms, polystyrene hydrocarbon chains.
