Abstract

ES DESCUBIERTO UN PROCESO PARA PRODUCIR UN POLIMERO BASADO DE ESTIRENO QUE TIENE UNA CONFIGURACION SINDIOTACTICA ALTA, COMPRENDIENDO POLIMERIZAR UN MONOMERO BASADO DE ESTIRENO CON ADICCION DE CATALIZADOR EN TALES CANTIDADES QUE LA CONVERSION LLEGA A SER DEL 2 AL 50% TREINTA MINUTOS DESPUES DE INICIARSE LA POLIMERIZACION, Y ENTONCES CONTINUAR LA POLIMERIZACION CON ADICCIONES DE LOS CATALIZADORES CUANDO LA CONVCERSION EXCEDE EL 10%. ACORDE AL PROCESO, LA PRODUCTIVIDAD PUEDE SER MEJORADA MIENTRAS FACILMENTE SE ALCANZA EL FUNCIONAMIENTO SEGURO DEL REACTOR Y EL CONTROL AFORTUNADO DEL CALOR DE REACCION.
