METHOD OF PREPARING A STABLE SUSTAINED LOAD FLOCULADAS CONTAINING PARTICLES OF A SIZE DISTRIBUTION OF SPECIFIC PARTICLES FOR USE IN PROCESSES OF MANUFACTURING PAPER AND METHOD OF PREPARING A STABLE SUSTAINED LOAD FLOCULADAS PARTICLES THAT WERE DISPERSED USING A HIGH LOAD FOR USE IN PROCESSES FOR THE PRODUCTION OF PAPER

A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises sequential addition of a first flocculating agent to an aqueous dispersion of filler particles followed by shearing of the dispersion， followed by addition of a second flocculating agent to the dispersion and further shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution. In addition， a neutralizing coagulant can be added to the dispersion to partially or completely neutralize the charge of the filler before the first flocculating agent is added A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises sequential addition of a first flocculating agent to an aqueous dispersion of filler particles followed by shearing of the dispersion， followed by addition of a second flocculating agent to the dispersion and further shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution.
