Abstract
Se describe un procedimiento para la obtencion de homopolímeros y/o copolímeros en solucion mediante la aplicacion de un compuesto que contiene un átomo de fosforo de grado de oxidacion inferior a 5 en cantidad de 0.005 a 0.49 átomos de fosforo por mol de insaturacion a polimerizar en ausencia de cualquier agente de descomposicion de agua oxigenada en radicales libres así como en ausencia de agente de transferencia. También se describen polímeros de contenidos reducidos de monomeros residuales obtenidos mediante el procedimiento así como sus usos.
