Abstract
Un procedimiento para preparar copolímeros no saturados de alto peso molecular, vulcanizables con los ingredientes empleados normalmente para los cauchos no saturados, partiendo de copolímeros saturados amorfos, homogéneos, exentos de homopolímeros (2) en que la cadena consiste substancialmente de una sucesión de unidades monoméricas de etileno, propileno y/o butano, caracterizado por el hecho de que las instauraciones se introducen en el copolímero saturado de partida por cloración de este último hasta contenidos de cloro inferiores al 5% en peso y cuidadosa deshidrocloración sucesiva a temperaturas elevadas, superiores a 160ºC, en presencia o ausencia de catalizadores, hasta que el cloro, combinado quede eliminado casi por completo.
