Résumé

L'invention porte sur un procédé de polymérisation afin d'extraire un poly(1,4-dioxan-2-one) thermique stabilisé et un copolymère de monomère d'ester cyclique au moyen d'un catalyseur/initiateur de coordination-insertion. 1,4-dioxan-2-one et le monomère d'ester cyclique contenant chacun moins de 100-ppm d'eau et possédant une valeur acide inférieure à 0,5 mg KOH/g, et de préférence moins de 0,2 mg KOH/g, sont copolymérisés. De préférence, le monomère d'ester cyclique est e-caprolactone et la réaction se fait dans une extrudeuse.
