Abstract

UNA PARTICULA ADITIVA REVESTIDA APROPIADA PARA USAR DURANTE LA POLIMERIZACION DE LA OLEFINA, INCLUYENDO LA PARTICULA UN NUCLEO CON AL MENOS UN ADITIVO Y UN REVESTIMIENTO INCLUYENDO AL MENOS UNA CERA SOLIDA A TEMPERATURA DE POLIMERIZACION. TAMBIEN SE DESCRIBE UN PROCESO PARA PRODUCIR DICHAS PARTICULAS, INCLUYENDO LAS FASES DE FUSION DE LA CERA DLE REVESTIMIENTO, LA FLUIDIFICACION DE LAS PARTICULAS DEL ADITIVO CON UN GAS CALIENTE, LA PULVERIZACION DE LA CERA FUNDIDA SOBRE LAS PARTICULAS DEL ADITIVO FLUIDIFICADAS Y CALENTADAS Y EL MANTENIMIENTO DE LAS PARTICULAS DEL ADSITIVO FLUIDIZADO A TAL TEMPERATURA QUE SE FORMEN PARTICULAS ADITIVAS DE REVESTIMIENTO DISUELTAS. ENTONCES LAS PARTICULAS DEL ADITIVO DEL REVESTIMIENTO ASI PRODUCIDAS PROPORCIONAN UNA ESTABILIZACION DE UN POLIMERO DE OLEFINA DE UN POLIMERO DE OLEFINA DURANTE LA REACCION DE POLIMERIZACION.
