Abstract

Los polvos de polímero que son redispersables en un medio acuoso se preparan secando una dispersion de polímero acuosa cuyas partículas de polímero dispersas en el medio acuoso tienen una carga superficial eléctrica positiva o negativa, con la adicion de un polielectrolito soluble en agua como el auxiliar de secado, la carga eléctrica del poli-ion siendo opuesta a la carga superficial eléctrica de las partículas de polímero dispersas.
