Abstract

Se describe un método para la produccion de poli(trifluoroacetato de vinilo) y copolímeros del mismo con ésteres de vinilo. El poli(trifluoroacetato de vinilo) (PVTFA) se obtiene con un rendimiento relativamente alto bajo condiciones moderadas mediante el uso de dioxido de carbono bajo condiciones atmosféricas como solvente. La síntesis del PVTFA sindiotáctico a escala comercial sin el uso de solventes ambientalmente peligrosos se hace posible mediante la invencion, la cual proporciona una ruta conveniente para el alcohol polivinilico sindiotáctico.
