Abstract

Se preparan látices a base de dienos conjugados mediante polimerizacion por emulsion, dosificándose los monomeros a ser polimerizados a latax de siembra dispuesto de antemano, en presencia de un activador formador de radicales y de un emulsionante, de tal manera que la proporcion entre la velocidad de polimerizacion de los monomeros y la velocidad de alimentacion de los monomeros sea menor que 0,7:1 y llevandose a cabo la polimerizacion hasta una conversion de los monomeros de >=95% a temperaturas de 10 a 85 degree C, controlandose la dosificacion del emulsionante de tal manera que el tamaño de partículas final (TGL) del latex a ser fabricado esté dado por la siguiente ecuacion: TGL = TGS * (mL/DL) 1/3 ((mS/DS)1/3, con DL= Densidad de las partículas de latex en el latex a ser fabricado, DS= Densidad de las partículas en la siembra empleada, mL= Masa de las partículas de latex en el latex a ser fabricado, mS= Masa de las partículas en la siembra empleada, TGL= Tamaño de las partículas de latex a ser fabricado, TGS= Tamaño de las partículas de la siembra empleada.
