Abstract

La presente invencion se refiere a un método para llevar a cabo la polimerizacion cationica de un monomero en dioxido de carbono. El método incluye los pasos de (a) proveer una mezcla de reaccion que comprende dioxido de carbono, un monomero, un catalizador y un iniciador de polimerizacion cationica, en donde el iniciador de polimerizacion cationica puede iniciar la polimerizacion cationica del monomero; (b) polimerizar el monomero en la mezcla de reaccion para formar un polímero.
