Abstract

PROCESO PARA POLIMERIZAR ANIONICAMENTE UN MONOMERO 1,3 DIENO CONJUGADO, CONSISTE EN CONTACTAR EL MONOMERO EN UN DISOLVENTE DE HIDROCARBONO INERTE CON UN INICIADOR DE ETER DE SILILO MONOFUNCIONAL DE FORMULA GENERAL R1R2R3SI R1 A R3 SON SELECCIONADOS INDEPENDIENTEMENTE DE GRUPOS SUSTITUYENTES ORGANICOS MONOVALENTES Y A ES UN GRUPO DE PUENTE DE HIDROCARBONO DE CADENA CORTA, PARA DAR UN POLIDIENO CON UN PESO MOLECULAR NORMAL DE 1.000-10.000, UN CONTENIDO ALTO NORMAL 1,4 DE 90% Y UNA POLIDISPENSIDAD NORMAL DE 1,15. LOS EXTREMOS REACTIVOS DE LAS CADENAS DEL POLIMERO VIVO PUEDEN TERMINARSE CON UN GRUPO REACTIVO COMO HIDROXILO TRATANDO EL POLIMERO CON OXIDO DE ETILENO. LA CONSIGUIENTE ELIMINACION DE LOS GRUPOS DE EXTREMO SILILO RELATIVAMENTE NO REACTIVOS DEL POLIMERO POR REACCION CON FLUORURO TETRA INADO EN HIDROXI EXTENSIBLE EN CADENA DIFUNCIONAL UTIL COMO UN PREPOLIMERO AGLOMERANTE DE CAUCHO.
