Abstract
EL PROCEDIMIENTO SIRVE PARA LA FABRICACION DE PIEZAS MOLDEADAS DE UNA ALEACION POLIMERA CON MORFOLOGIA POLIFASICA, EN EL QUE LA ALEACION POLIMERA ES PRODUCIDA EN UNA FASE DEL PROCEDIMIENTO DE MOLDEO POR INYECCION DE PIEZAS. PARA ELLO, SE AÑADEN UNOS POLIMEROS ELABORABLES TERMOPLASTICAMENTE Y POCO O NADA COMPATIBLES ENTRE SI, COMO GRANULADOS CON UN TAMAÑO DE GRANO DE 3 MM, EN UN EMBUDO DE UNA MAQUINA DE MOLDEO POR INYECCION, DESPUES DE LO CUAL ESTOS SON PLASTIFICADOS, MEZCLADOS Y CONFORMADOS EN LA MISMA MAQUINA DE MOLDEO POR INYECCION, A CUYO EFECTO AL MENOS UNO DE LOS POLIMEROS UTILIZADOS ES CAPAZ, BAJO LAS CONDICIONES DE MOLDEO POR INYECCION, DE ASOCIARSE QUIMICAMENTE Y/O COPOLIMERIZARSE CON AL MENOS UNO DE LOS OTROS POLIMEROS. LAS ALEACIONES POLIMERAS OBTENIDAS NO SON EN LO QUE RESPECTA A SUS PROPIEDADES INFERIORES A LAS CORRESPONDIENTES ALEACIONES CONSEGUIDAS MEDIANTE LOS PROCEDIMIENTOS HABITUALES.
