Abstract

Método para encapsular material desmenuzado finamente dividido y producir microcápsulas, en las que dicho material desmenuzado queda rodeado por vainas polímeras, que comprende la preparación de una dispersión de ese material desmenuzado en un medio acuoso que contenga un precondensado de urea-formaldehído soluble en agua, caracterizado por las operaciones de incorporar en la dispersión un precondensado de melamina-formaldehído soluble en agua y un polímero también soluble en agua y capaz de ser transversalmente enlazado por tales precondensados; y condensar estos precondensados mediante catalizadores ácidos, con el resultante enlace transversal de dicho polímero alrededor del material desmenuzado, formándose así las mencionadas vainas polímeras.
