Abstract
METODO PARA LA TERMINACION DE POLIMEROS VIVIENTES, APLICABLE A MACROANIONES VIVIENTES QUE SE OBTIENEN POR POLIMERIZACION ANIONICA DE MONOMEROS DIENICOS Y/O VINILAROMATICOS. CONSISTE EN LA INTRODUCCION EN LA MEZCLA DE POLIMERIZACION, EN UNA SOLA ADICION O EN ADICIONES PARCIALES Y EN EL INSTANTE DESEADO, DE UN AGENTE DE ACOPLAMIENTO ELEGIDO ENTRE ALGUNO DE LOS COMPUESTOS REPRESENTADOS EN LA FIG. (I). LA OPERACION SE LLEVA A CABO EN UN DISOLVENTE INERTE, COMO UN HIDROCARBURO PARAFINICO, CICLOPARAFINICO O AROMATICO, EN PRESENCIA DE INICIADOR O EN AUSENCIA DE LOS MISMOS, A UNA TEMPERATURA COMPRENDIDA ENTRE 50JC Y 150JC.
