Abstract
Un método para obtener partículas poliméricas, en el cual el material polimérico chatarra, material polimérico virgen, y mezclas de los mismos, sonsuministrados a los tornillos interengranados de una extrusora que son hechos rotar de modo de transportar el material polimérico a lo largo de su longitud ysometer el material polimérico a una pulverizacion por corte en estado solido y a una compatibilizacion in situ de los polímeros, si hay dos o más polímerosincompatibles presentes. Se producen partículas pulverizadas uniformes, sin la adicion de un agente de compatibilizacion. Las partículas pulverizadas sondirectamente procesables en estado de fusion (como materia prima en forma de polvo), y, lo que es sorprendente, permiten obtener un producto con un color clarosustancialmente homogéneo. Las partículas pulverizadas también pueden ser mezcladas más íntimamente que las mezclas que son provistas mediante solamente elmezclado de fusion, y pueden ser procesadas en estado de fusion sin una demora significativa para lograr la inversion de las fases. Las partículas pulverizadastambién proveen una micro-estructura estable.
