Description
The thermally instable solution of a material intended for gelation and of hexamethylene tetramine and/or urea is dispersed in a heated dispersion medium immiscible with water. Gel particles formed are separated from the dispersion medium, incorporated in oil at a temperature of 1O to 60 degC and cooled in this bath to room temperature. The spherical gel particles formed show increased resistant to cracking and destruction in further production operations. (M.S.)
