Abstract

Se da a conocer un método para remover los oligomeros de partículas de polímero de alfa-olefina esencialmente cristalinas sin tener que fundir las partículas. El método comprende fluidizar un lecho de partículas con un gas, en donde son solubles los oligomeros, cuyo lecho está a una temperatura a la cual las partículas no son pegajosas, pero por lo menos los oligomeros de peso molecular más bajo se evaporarán de las mismas, y mantener las partículas en el lecho fluidizado hasta que una porcion considerable de los oligomeros se haya evaporado y se hayan removido del lecho mediante el gas de fluidizacion. Regulando la temperatura del lecho y el tiempo de permanencia de las partículas en el lecho, se pueden controlar la proporcion y longitud de cadena de los oligomeros removidos.
