Abstract

PROCEDIMIENTO PARA LA PREPARACION EN MICROSUSPENSION DE LATEX DE HOMO- Y CO-POLIMEROS DE CLORURO DE VINILO UTILIZABLES COMO PRODUCTOS DE SIEMBRA, CUYAS PARTICULAS TIENEN UN DIAMETRO MEDIO COMPRENDIDO ENTRE 0,2 Y 0,8 MICRAS Y QUE CONTIENEN AL MENOS UN INICIADOR DE POLIMERIZACION ORGANOSOLUBLE SEGUN EL CUAL REALIZA UNA DISPENSION FINA DEL O DE LOS MONOMEROS CORRESPONDIENTES EN UNMEDIO ACUOSO QUE CONTIENEN AL MENOS UN EMULSIONANTE ANIONICO ASOCIADO CON AL MENOS UN EMULSIONANTE NO IONICO, EN PRESENCIA DE 0,004 A 0,16 POR CIENTO, EN PESO CON RELACION AL O LOS MONOMEROS, DEL CITADO INICIADOR EXPRESADO EN OXIGENO ACTIVO, A CONTINUACION SE REALIZA UNA OPERACION DE POLIMERIZACION, A TEMPERATURA PROXIMA A O1, SOBRE EL MEDIO REACCIONAL ASI FORMADO. ANTES DE REALIZAR LA DISPERSION DE O DE LOS MONOMEROS SE AGREGA PARABENZOQUINONA AL MEDIO ACUOSO Y EN EL TRANSCURSO DE LA OPERACION DE POLIMERIZACION SE AGREGA IGUALMENTE PARABENZOQUINONA, DE FORMA CONTINUA, AL MEDIO REACCIONAL, CUANDO LA TEMPERATURA O2 DELMEDIO REACCIONAL SEA TAL QUE LA DIFERENCIA O2 01 SEA SUPERIOR A UN VALOR ELEGIDO EN EL INTERVALO QUE VA DEL 0 A B5JC Y, PREFERENTEMENTE, DE 0 A B2JC, TOMANDO O1 VALORES GENERALMENTE COMPRENDIDOS ENTRE 30 Y 65JC.
