Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLVOS DE CAUCHO DE LIBRE FLUIDEZ, CON PARTICULAS CUYO DIAMETRO ESTA COMPRENDIDO ENTRE 0,01 Y 10 MM. CONSISTE EN ROMPER TOTALMENTE LAS PARTICULAS DEL LATEX DE UN CAUCHO, QUE SE COMPONEN FUNDAMENTALMENTE DE UN 80-99% DE CAUCHO DE ACRILATO, CON UNA TEMPERATURA DE TRANSICION CRISTALINA INFERIOR A 0<025>C, Y UN 1-20% DE POLIMERO INJERTADO, CON TEMPERATURAS DE TRANSICION CRISTALINA SUPERIORES A 20<025>C; LA ROTURA SE PRODUCE POR SUSPENSION DEL CAUCHO EN AGUA. POSTERIORMENTE SE AÑADEN A LA SUSPENSION DE 2 A 20% DE UNO O VARIOS MONOMEROS DE VINILO, Y LOS MONOMEROS SE POLIMERIZAN DESPUES DE AÑADIR UN CATALIZADOR POR RADICALES LIBRES. >ESTOS POLVOS DE CAUCHO TIENEN APLICACIONES PARA FABRICACION DE ELASTOMEROS, GOMAS, MATERIALES SINTETICOS ALTAMENTE FLEXIBLES, ETC.
