Abstract

PROCEDIMIENTO DE BROMACION CONTINUA DE CAUCHO BUTILICO CON OBJETO DE OBTENER UN POLIMERO CON UNA FRACCION SUSTANCIAL DEL BROMO EN LA POSICION ALILICA PRIMARIA. CONSISTE EN PONER EN CONTACTO EL POLIMERO SUSTANCIALMENTE LIBRE DE CAPTADORES DE ACIDO, A TEMPERATURA ELEVADA, Y EN MEDIO ACIDO CON UN AGENTE DE BROMACION SELECCIONADO ENTRE BROMO GASEOSO O LIQUIDO, CLORURO DE BROMO, BROMURO DE AZUFRE Y N-BROMOSUCCINIMIDA, EN UN DISPOSITIVO DE FLUJO CONTINUO PROVISTO DE MEDIOS PARA SEPARAR LOS SUBPRODUCTOS DE REACCION Y EL AGENTE DE BROMACION QUE NO HAYA REACCIONADO, DEFORMAR Y ROMPER LA SUPERFICIE DEL POLIMERO BROMADO E INYECTAR GAS INERTE CON OBJETO DE NEUTRALIZAR EL POLIMERO BROMADO.
